A number of changes in this release were contributed by Cydrak in the WIP thread, who described his changes from r09/r10 thusly: - Call cpu.synchronize_coprocessor() on external R/W to avoid missing data - Sign-extend K, L before multiplying - Load IDB before ALU. Supports the MOV A, d; XOR A, A idiom which is all over the place - Use 16-bit types in flag checks (notably Z) - Flags mostly unified; hopefully at least OV0 and SGN work - Carry-in comes from the *other* accumulator's flags, this is used for long arithmetic - CMP is ~q (see the many CMP A; INC A where values get negated) - SHR1 is arithmetic shift and retains the sign bit (Mario Kart sprites and physics are broken without it) - SHL1 has carry-in per the datasheet, it doesn't seem to be used though - XCHG probably byteswaps, but it's not used either - Reversed DR external R/W order again, big-endian seems to break it byuu described the remaining changes: You do not need the XML files anymore, bsnes will automatically choose the new uPD module, and look for dsp1b.bin. If you make your own XML file, you can force the old HLE mode, or use a differently-named PROM. If and when we get the DSP-2,3,4 modules, bsnes v072.11 and above should already be able to run them, assuming no more emulation core bugs. |
