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