Gb, gba, nes and snes are emulators for the Nintendo Game Boy
and Game Boy Color (GB and GBC), Nintendo Game Boy Advance (GBA),
Nintendo Entertainment System (NES), and Super Nintendo Entertainment
System (SNES). They execute the romfile given as an argument.
The z, x, a, s, q, w, return and shift keys
correspond to B, A, Y, X, L1, L2, Start and Select, respectively.
F1 Pause the emulator. If already paused it will step one video frame.
F5 Save the current state in gb.save / gba.save / nes.save / snes.save.
F6 Load the current state from gb.save / gba.save / nes.save / snes.save.
F12 Toggle the emulator's speedometer. It shows in the upper left, off–viewport corner, the ratio between the expected and observed time it took to draw 60 frames.
t Toggle tracing of the emulator.
` It uncaps the 60fps frame rate and lets emulation go as fast as possible.
Esc Pause the emulator.
Del Exit the emulator.
Command line options:
–b Location of the GBA BIOS file (required to operate the emulator). Default is /sys/games/lib/gbabios.bin.
–s Save format used by the original game. Valid formats are: eeprom4, eeprom64, sram256, flash512, flash1024. The number corresponds to the size, in kilobits, of the save file. By default, the emulator attempts to automatically detect the save format, but does not always succeed. Some roms require a specific
–o Hide the top and bottom eight pixels (overscan area), like a real television would.
–s Save contents of battery backed SRAM (used by some games for savegames) as a file (gb and snes automatically detect if this is needed).
SRAM saving on the NES only functions when the –s option is used.
The SNES horizontal hires mode is supported only with –2 scaling.
All emulators assume a North American (i.e. NTSC) system. PAL games (and in some cases Japanese games) are not supported.
The serial link emulation has issues with desynchronization in timing dependent scenarios.
