Usage\n\nNow with this tool it is possible to convert from .fas symbols file format.\n```\n.\\FasToSym -i [filename].fas -t [outputType]\n```\nTo for example the one accepted by No$gba like this:\n```\neg: .\\FasToSym -i mygame.fas -t nocashgba\n```\nThis should generate in the same folder with the same name but with the extension .SYM.\n\n## 2. Output files\n\nWhen developping homebrew for the Nintendo Game Boy Advance using FASMARM, https://arm.flatassembler.net/, it is important to debug with symbols. So in order to generate them:\n\n```\n./fasmarm.exe main.asm gba_game.gba -s mygame.fas\n```\nThe fas symbol file is not compatible with any of the GBA amulators so in order to convert it to for example No$Gba or Mesen (these two emulators have good debugging tool).\n\n### 2.1 GBA symbols for No$Gba.\n\nhttps://problemkaputt.de/gba.htm\n\nTo generate for this emulator use the the following command line:\n```\n.\\FasToSym -i mygame.fas -t nocashgba\n```\nThe documentation for its sym file format is here: https://problemkaputt.de/gbahlp.htm#symbolicdebuginfo\n\n### 2.2 GBA symbols for Mesen2.\n\nhttps://www.mesen.ca/\n\nTo generate for this emulator use the the following command line:\n\n```\n.\\FasToSym -i mygame.fas -t mesen\n```\nThe documentation for its sym file format is here: https://www.mesen.ca/docs/debugging/debuggerintegration.html#mesen-label-files-mlb\n\n\n\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdarkkodkod%2Ffastosym","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdarkkodkod%2Ffastosym","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdarkkodkod%2Ffastosym/lists"}
