fb9dddc360 dumb copypasta bug of the year. 2017-02-27 21:30:32 +01:00

8c2572e354 correct VRAM emulation. 
there is room for optimizations esp. in the GPU drawing routines.

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

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

15c8d59e2b vertex colors, with Gouraud shading and all 
has yet to be checked for whether it's accurate, optimized, etc...

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

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

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.
