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.

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

* fix cart DMA for ARM9.

StapleButter f4335b9292 better save support. not hardcoded filename, support for non-tiny EEPROM and Flash, attempt at autodetecting the right memory type. 2017-02-03 16:57:31 +01:00
StapleButter 282dcdece3 * make direct boot less shitty.
* add main RAM mirror at 0x02800000 for ARM7.

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.

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.
