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 1×.

-2

Scale the window 2×.

-3

Scale the window 3×.

-4

Scale the window 4×.

-5

Scale the window 5×.

-6

Scale the window 6×.

-b biosfile, --bios biosfile

Specify a BIOS file to use during boot. If this flag is omitted, 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 status 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:

DEBUGGER

When mgba is run with the -d option, the command-line debugger is enabled. 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 specified, only disassemble the current address.

h[elp]

Print help.

i[nfo]
status

Print the current contents of general-purpose registers and the current 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 directory. 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.
