.gitignore remove unneeded files. will stop melonDS.depend from polluting commit diffs. 2017-03-04 20:46:58 +01:00
ARM_InstrTable.h blarg 2017-02-01 00:31:23 +01:00

CP15.cpp better save support. not hardcoded filename, support for non-tiny EEPROM and Flash, attempt at autodetecting the right memory type. 2017-02-03 16:57:31 +01:00
CP15.h move TCM shit to CP15.cpp. closer to the real thing (for example now DMA can't access TCM, etc). 2017-01-30 19:11:29 +01:00
DMA.cpp * fixes to GXFIFO IRQ. refine IRQ support a bit. 2017-03-03 00:48:26 +01:00

melonDS

DS emulator, sorta

the goal is to do things right and fast, akin to blargSNES (but hopefully better)

but also to have fun coding this shit

LOVE MELONS

NO ASKING ROMZ!! ILLEGAL

license is GPL. don't steal the code.

how to use:

melonDS requires BIOS/firmware copies from a DS. Files required:

  • bios7.bin, 16KB: ARM7 BIOS
  • bios9.bin, 4KB: ARM9 BIOS
  • firmware.bin, 256KB: firmware

note: the DS-mode firmware in the 3DS isn't bootable, it only contains the bare minimum to run games.

ROM filename is currently hardcoded, check NDS.cpp for the required filename. this will eventually be addressed.

TODO LIST

  • sorta-UI (ie not hardcode ROM name)
  • 3D engine
  • sound
  • wifi
  • other non-core shit (debugger, graphics viewers, cheat crapo, etc)

IMMEDIATE TODO LIST (prior release 1.0)

  • UI
  • some polish to the 3D engine
  • make timers suck less

TODO LIST FOR LATER

  • sound
  • more 3D engine features
  • hardware renderer for 3D
  • wifi
  • maybe emulate flashcarts or other fancy hardware
  • big-endian compatibility (Wii, etc)
  • LCD refresh time (used by some games for blending effects)
