StapleButter 383093c5ff make NEG update flags correctly (oops). 
also misc graphics notes added.
 2017-03-06 18:13:57 +01:00
StapleButter 52d866fa17 remove unneeded files. will stop melonDS.depend from polluting commit diffs. 2017-03-04 20:46:58 +01:00
StapleButter 8c7b7e2327 temp. hack preventing evil out-of-bounds write 2017-03-04 15:34:07 +01:00
StapleButter f8770dc8fe don't blend semitransparent sprites with everything 2017-03-04 14:51:48 +01:00
StapleButter b6e12e0c18 * fix a few bugs related to 2D GPU registers (so there are atleast some of the graphics tests that pass) 
* less shitty texture mapping (and perspective-correct interpolation in general). extra bonus is that it also takes less divisions.

StapleButter fb9dddc360 dumb copypasta bug of the year. 2017-02-27 21:30:32 +01:00
StapleButter 8c2572e354 correct VRAM emulation. 
there is room for optimizations esp. in the GPU drawing routines.
 2017-02-27 21:26:11 +01:00
StapleButter dadf1eb5a5 fixes to 3D rendering. polygons are almost pixel-perfect. clipping still doesn't get colors quite right. 2017-02-20 18:46:44 +01:00

StapleButter cca0a71d81 emulate DMA timings. 
keeps games from overflowing the GXFIFO... when they aren't fucking dumb.
 2017-02-17 05:33:37 +01:00
StapleButter abd2cb444b improve 3D renderer precision. not perfect, but not bad at all. 2017-02-17 04:07:00 +01:00

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.
 2017-02-11 03:54:08 +01:00
StapleButter 78f49d061a base for software renderer 2017-02-10 16:50:26 +01:00

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. 
* fix cart DMA for ARM9.
