1f5faf8291 TSC support, touchscreen input. not perfect but for now this will do. 2017-02-01 00:24:36 +01:00

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

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.

c3e2f7ad9b * fix VRAM address calculation for GPU A 
* add support for mode 5

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.

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

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

711375c0be BG scroll. also fix silly bug. 2017-01-20 15:27:56 +01:00

7dba0121cb fix bug with ALU operations and shift operands, where the shift operation could obliterate the carry flag 
also, misc shit

3e5e8f60c4 * some basic BG display code 
* basic, frozen-in-time RTC
* power management device

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.
