MGBA(6) Games Manual MGBA(6) NAME mgba -- Game Boy Advance emulator SYNOPSIS mgba [-123456dfg] [-b biosfile] [-C option=value] [-c cheatfile] [-l loglevel] [-p patchfile] [-s n] [-t statefile] file DESCRIPTION mgba is a Game Boy Advance emulator. The options are as follows: -1 Scale the window 1x. -2 Scale the window 2x. -3 Scale the window 3x. -4 Scale the window 4x. -5 Scale the window 5x. -6 Scale the window 6x. -b biosfile, --bios biosfile Specify a BIOS file to use during boot. If this flag is omit- ted, mgba will use the BIOS specified in the configuration file, or a high-level emulated BIOS if none is specified. -C option=value, --config option=value Override the given config option with value. -c cheatfile, --cheats cheatfile Apply cheat codes from cheatfile. -d Start emulating via the command-line debugger. -f Start the emulator full-screen. -g Start a gdb(1) session. By default the session starts on port 2345. -l loglevel Log messages during emulation to stdout. loglevel is a bitmask defining which types of messages to log: • 1 - fatal errors • 2 - errors • 4 - warnings • 8 - informative messages • 16 - debugging messages • 32 - stub messages for unimplemented features • 64 - in-game errors The default is to log warnings, errors, fatal errors, and sta- tus messages. -p patchfile, --patch patchfile Specify a patch file in BPS, IPS, or UPS format. -s n, --frameskip n Skip every n frames. -t statefile, --savestate statefile Load initial game state from statefile. CONTROLS The default controls are as follows: A x B z L a R s Start <Enter> Select <Backspace> Load state F1-F9 Save state <Shift>-F1-F9 Frame advance <Ctrl>-n DEBUGGER When mgba is run with the -d option, the command-line debugger is en- abled. It supports the following commands: b[reak] address b[reak]/a address b[reak]/t address Set a breakpoint - ARM (`/a'), Thumb (`/t'), or the current CPU mode - at address. c[ontinue] Continue execution. d[elete] address Delete a breakpoint at address. dis[asm] [address [count]] dis[asm]/a [address [count]] dis[asm]/t [address [count]] dis[assemble] [address [count]] dis[assemble]/a [address [count]] dis[assemble]/t [address [count]] Disassemble count instructions starting at address, as ARM (`/a'), Thumb (`/t'), or the current CPU mode. If count is not specified, only disassemble the instruction at address. If address is not spec- ified, only disassemble the current address. h[elp] Print help. i[nfo] status Print the current contents of general-purpose registers and the cur- rent program state register, and disassemble the current instruction. n[ext] Execute the next instruction. p[rint] value ... p[rint]/t value ... p[rint]/x value ... Print one or more values as binary (`/t'), hexadecimal (`/x'), or decimal. q[uit] Quit the emulator. reset Reset the emulation. r/1 address r/2 address r/4 address Read a byte (`/1'), halfword (`/2'), or word (`/4') from address. w[atch] address Set a watchpoint at address. w/1 address data w/2 address data w/4 address data Write data as a byte (`/1'), halfword (`/2'), or word (`/4') to address. w/r register data Write data as a word to register. x/1 address [count] x/2 address [count] x/4 address [count] Examine count bytes (`/1'), halfwords (`/2'), or words (`/4') from address. If count is not specified, examine 16 bytes, 8 halfwords, or 4 words. ENVIRONMENT XDG_CONFIG_HOME The location where mgba will look for the configuration direc- tory. If not set, ~/.config is used. FILES $XDG_CONFIG_HOME/mgba/config.ini Default mgba configuration file. portable.ini If this file exists in the current directory, mgba will read config.ini from the current directory instead of $XDG_CONFIG_HOME/mgba.
