PSP homebrew developer Brunni has just updated the MasterBoy emulator, bringing the application up to version 2.01.

This app is a PSP-based emulator for playing games from the Game Boy, Game Boy Color, Super Game Boy, Sega Master System (SMS), and Game Gear handhelds. MasterBoy's latest release is expected to carry the following tweaks:

• Finished the english documentation on how to colorize your games!
  
• This version fixes a bug with sound volume when loading RIN states.
• The file list can now display up to 1024 roms.
• Added a small debug mode for the kernel version (copy the EBOOT from the Kernel mode directory to your MasterBoy directory on the PSP - this version runs significantly slower, so use it only for debugging and colorization). For people who reported me strange problems, press L+R+Triangle in the menu. It will show the available RAM. If you have the problem of save states not working after a while, please tell me how this value evolutes. Also, if this mode is enabled when going to Save states, SRAM, Save now, a message box with some information will appear, if you have the SRAM problem (not saving) please report to me the displayed text.
• Bugfixes
