050ba5dfbe some debuts of 3D drawing. 
it can draw non-strip polygons, filled with a fixed color. oh and it doesn't work if they're facing back.

2bd67aef64 calculate vertices. 
it doesn't do much, but hey, it's a start.

49fd4ccb45 * GXFIFO DMA (note: Mario Slam Basketball keeps overflowing the FIFO for whatever reason, probably lack of proper DMA timings) 
* start implementing matrix shit

796dc58f71 GXFIFO finished. hacktastic integration into the ARM9 loop. 2017-02-08 00:52:37 +01:00

971e7b7e89 well, GX FIFO base. noting that for now, it doesn't do much beyond getting full real quick. 
also make ROM loading fail gracefully if it shits itself, instead of entering an endless loop.

2b7fac05c7 rework FIFO crap so it can also be used for the GXFIFO crapo. 2017-02-07 22:41:33 +01:00

0562410de2 * lay base for 3D engine

* GPU-related notes
* readme update

86cdf28323 change how redrawing is done. fixes memory leak and other fun shit. 
calling GetDC() over and over again isn't a good idea.

3cf38e3e9d lil' hack. makes SM64DS go ingame. 2017-02-05 18:34:21 +01:00

1001df49ea support extended palette for 256-color sprites. 2017-02-05 18:23:03 +01:00

e88cf1b43d apparently when you set an out-of-bounds address for EEPROM, it should wrap around 
TODO: check if it also happens with Flash

also fix shit that could have later turned into memory leaks

ff3b60bc93 ARM7 BIOS read protect. 
(noting that Super Princess Peach reads from the BIOS. probably a bug)

5ccf56d21d * fix 'STMxx with base register included in register list' when base register is banked.

f4335b9292 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

03c1a9cbc8 more anti-crash. 
don't unmap VRAM in cases of overlaps. fixes NSMB minigames, for now.

9541d17c7c * implement the last missing instructions. QADD is not good according to ARMWrestler, but it doesn't make sense. TODO: investigate. 
* buttons A and B
* silence 'unknown IO write' for 3D GPU ports
 2017-01-31 18:41:31 +01:00

516bc30ee3 * very shitty implementation of save RAM. requires an existing save file for now. 
* refine some SPI code, too. mostly removing a useless function.
* support 16bit accesses to DMAxCNT registers.
 2017-01-31 17:34:17 +01:00

c3e2f7ad9b * fix VRAM address calculation for GPU A

12ebf83665 keep the GPU from crashing if there's no VRAM mapped, I guess. 
noting that the way it's accessing VRAM is grossly inaccurate.

594286ee5d * scheduler revamp, simpler design 
* fix dumb bug of the year: ARM LDR opcodes would accidentally read twice, which fucked with things like the IPC FIFO.

348bbd8cb8 move TCM shit to CP15.cpp. closer to the real thing (for example now DMA can't access TCM, etc). 
the code is shit. I would use templates if only it fucking worked without requiring the function body to be included in a .h.
 2017-01-30 19:11:29 +01:00

6f3b0498db start refactoring shit: more accurate timing and way of counting cycles. 2017-01-30 18:36:11 +01:00

14f1cec955 some beginning of sprite support: 16bit tiled sprites, not rotated or anything fancy 
also give it a version number
