StapleButter cca0a71d81 emulate DMA timings. 
keeps games from overflowing the GXFIFO... when they aren't fucking dumb.

StapleButter 15c8d59e2b vertex colors, with Gouraud shading and all 
has yet to be checked for whether it's accurate, optimized, etc...
 2017-02-11 04:10:59 +01:00
StapleButter 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.

Lioncash 896bb1b781 ARM: Fix out of bounds array indexing in RestoreCPSR 2017-02-09 08:18:05 -05:00
StapleButter 2bd67aef64 calculate vertices. 
it doesn't do much, but hey, it's a start.
 2017-02-09 02:39:52 +01:00
StapleButter 49fd4ccb45 * GXFIFO DMA (note: Mario Slam Basketball keeps overflowing the FIFO for whatever reason, probably lack of proper DMA timings) 
* start implementing matrix shit
 2017-02-08 21:30:10 +01:00
StapleButter 796dc58f71 GXFIFO finished. hacktastic integration into the ARM9 loop. 2017-02-08 00:52:37 +01:00
StapleButter 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.
 2017-02-07 23:31:21 +01:00
StapleButter 2b7fac05c7 rework FIFO crap so it can also be used for the GXFIFO crapo. 2017-02-07 22:41:33 +01:00
StapleButter 0562410de2 * lay base for 3D engine 
* add failure reporting to Init functions, and DeInit functions
* GPU-related notes
* readme update
 2017-02-07 22:23:46 +01:00
StapleButter 86cdf28323 change how redrawing is done. fixes memory leak and other fun shit. 
calling GetDC() over and over again isn't a good idea.
 2017-02-06 00:07:22 +01:00
StapleButter 3cf38e3e9d lil' hack. makes SM64DS go ingame. 2017-02-05 18:34:21 +01:00
StapleButter 1001df49ea support extended palette for 256-color sprites. 2017-02-05 18:23:03 +01:00
StapleButter 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
 2017-02-05 17:45:17 +01:00
StapleButter ff3b60bc93 ARM7 BIOS read protect. 
(noting that Super Princess Peach reads from the BIOS. probably a bug)
 2017-02-05 17:15:17 +01:00
StapleButter 5ccf56d21d * fix 'STMxx with base register included in register list' when base register is banked.

StapleButter 64f9822db6 fix ARM7 VRAM 2017-02-01 19:30:57 +01:00
StapleButter e028973caa this is not how sprite priorities work, you derp 2017-02-01 18:47:13 +01:00
StapleButter 03c1a9cbc8 more anti-crash. 
don't unmap VRAM in cases of overlaps. fixes NSMB minigames, for now.
 2017-02-01 17:05:12 +01:00
StapleButter 6d2092a106 blarg 2017-02-01 00:31:23 +01:00

StapleButter 548b8d99a6 sqrt crap 2017-01-31 21:53:45 +01:00
StapleButter 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
StapleButter 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
StapleButter c3e2f7ad9b * fix VRAM address calculation for GPU A 
* add support for mode 5
 2017-01-31 15:43:22 +01:00
StapleButter 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.
 2017-01-31 04:06:05 +01:00
StapleButter 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.
 2017-01-31 03:54:51 +01:00
StapleButter 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.
