 Changelog
 ---------
+1.35a
+  * PSP: fixed a bug which prevented to load any ROMs after testing the BIOS.
+  * PSP: fixed incorrect CZ80 memory map setup, which caused Z80 crashes and
+    graphics corruption in EU Mega CD model1 BIOS menus.
+  + PSP: added additional "set to 4:3 scaled" display option for convenience.
+  + Added an option to disable frame limitter (works only with non-auto frameskip).
+
 1.35
   + PSP port added. Lots of new code for it. Integrated modified FAME/C, CZ80 cores.
   + Some minor generic optimizations.
