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 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 e028973caa this is not how sprite priorities work, you derp 2017-02-01 18:47:13 +01:00
StapleButter 03c1a9cbc8 more anti-crash.

 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

* 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.
 2017-01-30 19:11:29 +01:00
StapleButter 6f3b0498db start refactoring shit: more accurate timing and way of counting cycles. 2017-01-30 18:36:11 +01:00

StapleButter 62ed28d5c8 rotscaled 16color sprites. about fucking time I get this shit working. 2017-01-21 17:06:54 +01:00
StapleButter 14f1cec955 some beginning of sprite support: 16bit tiled sprites, not rotated or anything fancy 
also give it a version number
 2017-01-21 03:36:14 +01:00
StapleButter 711375c0be BG scroll. also fix silly bug. 2017-01-20 15:27:56 +01:00
StapleButter 7dba0121cb fix bug with ALU operations and shift operands, where the shift operation could obliterate the carry flag 
also, misc shit
 2017-01-20 15:13:44 +01:00
StapleButter 3e5e8f60c4 * some basic BG display code 
* basic, frozen-in-time RTC
* power management device

StapleButter d7c1d2a2cd * start GPU shit: draw BG0 16-color. 
* fix a few DMA bugs.
* fix a bug where some code could still run right after a halt instruction.
* fix VRAM mapping, too. I'm an idiot.
