Genesis-Plus-GX/source/gx/gui/gui.c
ekeeke31 d66d747d98 - annual code cleanup ;-) 
- added port $3E emulation (SMS, GG)
- added SMS & GG BIOS support
- added an option to run BIOS without cartridge
- added separate ROM browsers for SG-1000, Master System, Game Gear & Mega Drive / Genesis
- changed Cheat menu icon
- moved ROM device selection (SD,USB,DVD) to menu options
- moved savestate compression/decompression out of emulator core
- removed useless background images & background color option
- prevented deletion of cheat files when no valid codes are found left
- added IOS patch on startup to fix Homebrew Channel network bug when <no_ios_reload> option is used
