This is yet another SEGA 8 bit and 16 bit console emulator.
|
||||
# Sonic's UGC for PSP
|
||||
|
||||
It can run games developed for most consumer hardware released
|
||||
by SEGA, up to and including the 32X:
|
||||
- **16 bit systems:** Mega Drive/Genesis, Sega/Mega CD, 32X, Pico
|
||||
- **8 bit systems**: SG-1000, SC-3000, Master System/Mark III, Game Gear
|
||||
A fork of PicoDrive for PSP, skinned to look like Sonic's Ultimate Genesis Collection
|
||||
|
||||
PicoDrive was originally created with ARM-based handheld devices
|
||||
in mind, but later received various cross-platform improvements
|
||||
such as SH2 recompilers for MIPS (mips32r2), ARM64 (armv8), RISC-V (RV64IM)
|
||||
and PowerPC (G4/2.03).
|
||||
### Why?
|
||||
|
||||
PicoDrive was the first software to properly emulate Virtua Racing and
|
||||
its SVP chip.
|
||||
In 2019 (when i originally had this idea) i had just gotten a PSP, and in 2016-2020 i had a copy of Sonic's UGC on the Xbox 360, i knew that the PSP was very much powerful enough to run the same library of games, and this was on the back of my head until August of 2024, when i finally gained enough skill to make this into a reality.
|
||||
|
||||
At present, most development activity occurs in
|
||||
[irixxxx's fork](https://github.com/irixxxx/picodrive);
|
||||
[notaz's repo](https://github.com/notaz/picodrive) is updated less frequently.
|
||||
**Fun Fact** - I did make a **terrible** version of this idea in 2019 with my limited brain, which i still have archived today, (i stretched the SUGC logo to fit on the PBP, changed the background which made the game list almost unreadable, and a few other horrible hacks), but, it didn't involve any source code. This time i'm doing it for real, redesigning the UI and open sourcing all of it
|
||||
|
||||
### Sega Pico and Storyware Pages
|
||||
### Downloads
|
||||
|
||||
PicoDrive can use Storyware pages and pad overlays in png format in the same
|
||||
directory as the cartridge image. The selected page is displayed automatically
|
||||
if the pen is used on the storyware or pad. Details about how to correctly name
|
||||
the pages can be found in the *How to run Sega Pico games* section in
|
||||
`platform/base_readme.txt`.
|
||||

|
||||
**Q: Will you make this for the European version of Sonic's UGC (Sega Mega Drive Ultimate Collection // SEGA MDUC)?**
|
||||
A: Originally i wasn't going to, but after making a separate branch to do it, i'm definitely going to release it. Up-to-date Development builds will ALWAYS be based on SUGC though.
|
||||
|
||||
### Compiling
|
||||
**Q: Will you make a PS2 Port? It looks really similar to the PSP version!**
|
||||
A: Never. I haven't owned a PS2 since 2013 (when i was a fucking baby) and don't plan to.
|
||||
|
||||
For platforms where release builds are provided, the simplest method is to
|
||||
use the release script `tools/release.sh`. See the script itself for details.
|
||||
To create platform builds run the command:
|
||||
**Q: How can i add more games?**
|
||||
A: Download or compile the Memory Stick version, go to or create the "rom" directory and add your games there, the file format doesn't matter
|
||||
|
||||
```
|
||||
tools/release.sh [version] [platforms...]
|
||||
```
|
||||
**Q: How do i compile on Windows?**
|
||||
A: Not supported. I haven't used Windows as my daily OS since 2021 and have no plans to go back. Modern Windows is terrible and i have no reason to switch back (the biggest hurdle was Camtasia, which i finally stopped using after 6 years). Just use a Linux VM if you can't make the switch
|
||||
|
||||
This will generate a file for each platform in the `release-[version]` directory.
|
||||
A list of supported platforms can be found in the release script.
|
||||
**Q: Does this work on PS Vita?**
|
||||
A: Yes, just use Adrenaline and you're good, both the ISO and Memory Stick versions should work with no problem.
|
||||
|
||||
These commands should create an executable for a unixoid platform not included in the list:
|
||||
**Q: Does this work on PPSSPP?**
|
||||
A: Absolutely! I used PPSSPP for testing the dev builds and it works flawlessly, but if you're gonna emulate SEGA Genesis games on an emulator, just use a normal Sega Genesis emulator, this is largely intended for people who own a PSP or PS Vita console.
|
||||
|
||||
```
|
||||
configure --platform=generic
|
||||
make
|
||||
```
|
||||
**Q: How did you get an uncompressed version of the SUGC Intro and Soundtrack**
|
||||
A: I ripped them myself from the Xbox 360 and PS3 version, just extract the files from the ISO and you should be good. ([Intro Video (X360)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/SGC2_ATTRACT.wmv) - [Background Theme (Retro Dreams) (X360)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/retro_dreams.xma) - [Background Video (X360)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/MAIN0001.wmv) - [SUGC Logo (PS3)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/SUGC_LOGO.PNG) - [SMDUC Logo (PS3)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/SMDUC_LOGO.PNG) - [XMB BGM (PS3)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/SND0.AT3) - [XMB BGM (PS3, converted to WAV)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/SND0.wav) - [XMB BGM (PS3, converted to MP3)](https://dl.raythefox.pw/Projects/Sonic%27s%20UGC%20for%20PSP/Assets/SND0.mp3))
|
||||
|
||||
To compile PicoDrive as a libretro core, use this command:
|
||||
|
||||
```
|
||||
make -f Makefile.libretro
|
||||
```

||||

||||
### Helix MP3 decoder for ARM
|
||||
|
||||
For 32 bit ARM platforms, the optimized helix MP3 decoder can be used to play
|
||||
MP3 audio files with CD games. Due to licensing issues, the helix source files
|
||||
cannot be provided here; if you have obtained the sources legally, place them in
|
||||
the `platform/common/helix` directory.
|
||||
|
||||
To compile the helix sources:
|
||||
|
||||
- Set the environment variable `CROSS_COMPILE` to your cross compiler prefix
|
||||
(e.g. `arm-linux-gnueabi-`)
|
||||
- Set the environment variable `LIBGCC` to your cross compiler's `libgcc.a`
|
||||
(e.g. `/usr/lib/gcc-cross/arm-linux-gnueabi/4.7/libgcc.a`)
|
||||
- Run the command:
|
||||
```
|
||||
make -C platform/common/helix CROSS_COMPILE=$CROSS_COMPILE LIBGCC=$LIBGCC
|
||||
```
|
||||
- Copy the resulting shared library named `${CROSS_COMPILE}helix_mp3.so` as
|
||||
`libhelix.so` to the directory containing the PicoDrive binary on the target device.
|
||||
|
||||
In addition, helix support must be enabled in PicoDrive itself by compiling with:
|
||||
|
||||
```
|
||||
make PLATFORM_MP3=1
|
||||
```
|
||||
|
||||
This switch is enabled automatically for Gamepark Holdings devices (`gp2x`,
|
||||
`caanoo` and `wiz`). Without installing `libhelix.so`, these devices will not play
|
||||
MP3 audio.
|
||||
|
||||
### Installing
|
||||
|
||||
The release script produces packages or zip archives which have to be installed
|
||||
manually on the target device. Usually this involves unpacking the archive or
|
||||
copying the package to a directory on either the internal device storage or an
|
||||
SD card. Device-specific instructions can be found on the internet.
|
||||
|
||||
|
||||
Send bug reports, fixes etc. to <derkub@gmail.com>
|
||||
**Q: How did you figure out this really confusing source code?**
|
||||
A: I admit that the PicoDrive source code is *almost* unreadable, and i definitely wouldn't recommend it to a beginner, but even if you are total trash at C code like i am, if you know where to look, it's not that hard, 99% of the changes were in the UI and the PSP-specific code, not on the emulator itself, i'm pretty sure it's possible to port this to Windows/Linux/PS2, but i have no desire in doing it myself, i can provide all of the design files, [my DMs are always open](https://raythefox.pw), message me and i'll be glad to help.

About PicoDrive
|
||||
---------------
|
||||
|
||||
#include "../README.md"
|
||||
|
||||
|
||||
How to make it run
|
||||
------------------
|
||||
|
||||
#ifdef GENERIC
|
||||
Extract the zip file into some directory and run PicoDrive from there.
|
||||
#endif
|
||||
#ifdef GP2X
|
||||
Extract all files to some directory on your SD and run PicoDrive.gpe from your
|
||||
GP2X/Wiz/Caanoo menu. The same .gpe supports GP2X F100/F200, Wiz and Caanoo,
|
||||
there is no need to use separate versions.
|
||||
#endif
|
||||
#ifdef GIZ
|
||||
First make sure you have homebrew-enabled Service Pack installed. Then copy
|
||||
PicoDrive.exe and KGSDK.dll to any place in your filesystem (both files must
|
||||
be in the same directory) and run PicoDrive.exe using the launcher of your choice
|
||||
(some of them might require renaming PicoDrive.exe to Autorun.exe, placing it in
|
||||
the root of SD, etc).
|
||||
#endif
|
||||
#ifdef PSP
|
||||
If you are running a custom firmware, just copy the whole PicoDrive directory to
|
||||
/PSP/GAME or /PSP/GAMEXXX directory in your memory stick (it shouldn't matter
|
||||
which one GAME* directory to use).
|
||||
#endif
|
||||
#ifdef PANDORA
|
||||
Just copy the .pnd to <sd card>/pandora/menu or <sd card>/pandora/desktop.
|
||||
#endif
|
||||
|
||||
Then load a ROM and enjoy! Cartridge ROMs can be in various common formats and
|
||||
can be zipped, one ROM file per zip. Certain extensions are used to detect the
|
||||
console the ROM is for (.sg, .sc, .sms, .gg, .smd, .md, .gen, .32x, .pco).
|
||||
For MSU games, load the .cue file and make sure the cartridge ROM has the same
|
||||
name and is in the same directory.
|
||||
Sega/Mega CD images can be in CHD, CUE+BIN/ISO or ISO/CSO+MP3/WAV format (read
|
||||
below for more details).
|
||||
|
||||
This emulator has lots of options with various tweaks (for improved speed mostly),
|
||||
but it should have best compatibility in it's default config. If suddenly you
|
||||
start getting glitches or change something and forget what, use "Restore defaults"
|
||||
option.
|
||||
|
||||
|
||||
How to run Sega/Mega CD games
|
||||
-----------------------------
|
||||
|
||||
To play any non-MSU CD game you need BIOS files. These files must be copied to
|
||||
#ifdef PANDORA
|
||||
<sd card>/pandora/appdata/picodrive/ directory
|
||||
(if you run PicoDrive once it will create that directory for you).
|
||||
#else
|
||||
#ifdef GENERIC
|
||||
the .picodrive directory in your home directory.
|
||||
#else
|
||||
the same directory as PicoDrive files.
|
||||
#endif
|
||||
#endif
|
||||
Files must be named as follows:
|
||||
|
||||
US: us_scd1_9210.bin, us_scd2_9306.bin, SegaCDBIOS9303.bin
|
||||
EU: eu_mcd1_9210.bin, eu_mcd2_9303.bin, eu_mcd2_9306.bin
|
||||
JP: jp_mcd1_9112.bin, jp_mcd1_9111.bin
|
||||
these files can also be zipped.
|
||||
|
||||
The game must be dumped to CHD, CUE+BIN or CUE+ISO format.
|
||||
ISO/CSO+MP3/WAV is also supported, but may cause problems.
|
||||
When using CUE/BIN, you must load .cue file from the menu, or else the emu will
|
||||
not find audio tracks.
|
||||
|
||||
|
||||
How to run Sega Pico games
|
||||
--------------------------
|
||||
|
||||
The Pico was special in that it had a large touchpad with an associated pen, and
|
||||
so-called storyware, a combination of a cartridge with a book with up to 6 pages
|
||||
on which the pen could also be used.
|
||||
|
||||
Most storywares used the touchpad with the pen as a pointer device, showing a
|
||||
pointer icon on the screen when the pen was on the touchpad which could be moved
|
||||
around. The pen has a dedicated button which was often used to select something
|
||||
under the pointer icon, much like a mouse button.
|
||||
However, a few games also had an overlay for the touchpad.
|
||||
|
||||
PicoDrive supports displaying both the storyware pages as well as a pad overlay.
|
||||
They must be in png format and named like the storyware ROM without the
|
||||
extension, plus "_<n>.png" for the storyware page <n>, and "_pad.png" for a pad
|
||||
overlay. Storyware page images should have an aspect ration of 2:1, pad images
|
||||
should have 4:3. All images can have arbitrary resolution and are automatically
|
||||
scaled to fit the screen.
|
||||
|
||||
There are 2 menu actions for switching to pages or pad which will automatically
|
||||
display the images if they are available. To allow for proper pen positioning
|
||||
there is also an action for having the pen on the page/touchpad or not. Pen
|
||||
positioning is done through the D-pad if the screen has been switched to either
|
||||
pages or pad.
|
||||
|
||||
|
||||
Other important stuff
|
||||
---------------------
|
||||
|
||||
* Sega/Mega CD: If the background music is missing, the CD image format may be
|
||||
wrong. Currently .cue/bin or .chd is recommended. Be aware that there are
|
||||
lots of bad dumps on the web, and some use mp3 format for audio, which often
|
||||
causes problems (see below).
|
||||
* While iso/mp3 format is supported, it's not recommended to use.
|
||||
Some of many problems with mp3 are listed below:
|
||||
* MP3s may be named incorrectly and will not play.
|
||||
* The game music may play too fast/too slow/out of sync, which means they
|
||||
are encoded incorrectly. PicoDrive is not a mp3 player, so all mp3s MUST
|
||||
be encoded at 44.1kHz stereo.
|
||||
* Sega/Mega CD: If your games hang at the BIOS screen (with planets shown),
|
||||
you may be using a bad BIOS dump. Try another from a different source,
|
||||
like dumping it from your own console.
|
||||
#ifdef GP2X
|
||||
* When using mp3s, use lower bitrate for better performance (96 or 128kbps
|
||||
CBRs recommended).
|
||||
* GP2X F100/F200: When you use both GP2X CPUs, keep in mind that you can't
|
||||
overclock as high as when using ARM920 only. For example my GP2X when run
|
||||
singlecore can reach 280MHz, but with both cores it's about 250MHz. When
|
||||
overclocked too much, it may start hanging and producing random noise, or
|
||||

# Sonic's UGC for PSP
|
||||
|
||||
A fork of PicoDrive for PSP, skinned to look like Sonic's Ultimate Genesis Collection
|
||||
|
||||
### Why?
|
||||
|
||||
In 2019 (when i originally had this idea) i had just gotten a PSP, and in 2016-2020 i had a copy of Sonic's UGC on the Xbox 360, i knew that the PSP was very much powerful enough to run the same library of games, and this was on the back of my head until August of 2024, when i finally gained enough skill to make this into a reality.
|
||||
|
||||
**Fun Fact** - I did make a **terrible** version of this idea in 2019 with my limited brain, which i still have archived today, (i stretched the SUGC logo to fit on the PBP, changed the background which made the game list almost unreadable, and a few other horrible hacks), but, it didn't involve any source code. This time i'm doing it for real, redesigning the UI and open sourcing all of it

### Q&A
|
||||
|
||||
**Q: Will you make this for the European version of Sonic's UGC (Sega Mega Drive Ultimate Collection // SEGA MDUC)?**
|
||||
A: Most likely not, the version i grew up with was SUGC and it doesn't hit the same for me, i did take a brief look on and it is largely the same, i'm just not bothered to do it at the moment.
|
||||
|
||||
**Q: Will you make a PS2 Port? It looks really similar to the PSP version!**
|
||||
A: Never. I haven't owned a PS2 since 2013 (when i was a fucking baby) and don't plan to.
|
||||
|
||||
**Q: How can i add more games?**
|
||||
A: Download or compile the Memory Stick version, go to or create the "rom" directory and add your games there, the file format doesn't matter
|
||||
|
||||
**Q: How do i compile on Windows?**
|
||||
A: Not supported. I haven't used Windows as my daily OS since 2021 and have no plans to go back. Modern Windows is terrible and i have no reason to switch back (the biggest hurdle was Camtasia, which i finally stopped using after 6 years). Just use a Linux VM if you can't make the switch
|
||||
|
||||
**Q: Does this work on PS Vita?**
|
||||
A: Yes, just use Adrenaline and you're good, both the ISO and Memory Stick versions should work with no problem.
|
||||
|
||||
**Q: Does this work on PPSSPP?**
|
||||
A: Absolutely! I used PPSSPP for testing the dev builds and it works flawlessly, but if you're gonna emulate SEGA Genesis games on an emulator, just use a normal Sega Genesis emulator, this is largely intended for people who own a PSP or PS Vita console.
|
||||
|
||||
**Q: How did you get an uncompressed version of the SUGC Intro and Soundtrack**
|
||||
A: I ripped them myself from the Xbox 360 version, just extract the files from the ISO and you should be good.

|
||||
|
||||
**Q: How did you figure out this really confusing source code?**
|
||||
A: I admit that the PicoDrive source code is *almost* unreadable, and i definitely wouldn't recommend it to a beginner, but even if you are total trash at C code like i am, if you know where to look, it's not that hard, 99% of the changes were in the UI and the PSP-specific code, not on the emulator itself, i'm pretty sure it's possible to port this to Windows/Linux/PS2, but i have no desire in doing it myself, i can provide all of the design files, [my DMs are always open](https://raythefox.pw), message me and i'll be glad to help.
