byuu says: Changelog: - renamed SRTC -> SharpRTC - renamed RTC4513 -> EpsonRTC (consistent with DSP naming schema) - full emulation of invalid BCD values for EpsonRTC - fixed EpsonRTC IRQ mask Remaining SPC7110 tasks: - RTC: test 30-second adjust with all values from 00-7f - RTC: hold is supposed to tick the clock one second after being released? - RTC: wait times are too long (need to use >32KHz oscillation to simulate it properly) - Data Port: test $4818 more thoroughly (not too important) - Decompression: test $480c more thoroughly (very important) - Decompression: perform some tests on DMA transferring data, especially with $4807 set Write-offs, at least for now: - Decompression: emulation of the crash/glitch behavior seen on the real chip when fed invalid data - Decompression: I can find no use of $4808 - ALU: Booth cycles for MUL/DIV (this could actually be rather important if the game reads simpler values quickly [some shoddy games did this with the CPU ALU]) - RTC: delay after hold release for $4841 accesses - RTC: 125uS delay after 30-second adjust that will screw with registers in odd ways if your read or write too soon - RTC: psychotic behavior of reading too early returning port address - 1 |
