Hm, looks like it communicates exclusively via DP. I logged all dsp accesses in bsnes and DR/SR are not touched even once by F1 ROC II. However once the race starts, there's a firework on DP.
I guess I'll have to implement it then

Trying it out now.
Do I also need to map the data RAM?

Is there enough memory to support the ST-0010 and ST-0011? It needs 52KB instead of 8KB per game, but the instruction set is the same, just with a new jump mechanism. Sadly no, the FPGA has roughly 36kB of block RAM. 17kB of those are always dedicated to MSU1 for data+sound buffers (MSU1 should be ...

Finished the uPD77C25 core. DSP1-4 work fine. (DSPx roms required.)

There will probably be a first batch of 100 sd2sneses this year, maybe another 100 next year. Not so sure yet.

OK, loss of sync might mean the SuperCIC has switched to "pair mode". It's a special mode that can (usually) be entered when there is a SuperCIC key present on the cartridge, with its pair mode configuration pin enabled. In pair mode, 50/60Hz can be remote controlled from the cartridge. Th...

Nope, the Wolfsoft mods are 100% correct. Klaus confirmed correct operation to me personally. ;) (and he shows in the videos that they work even with a US SNES) You shouldn't use terribly thin wire for the power supply pins (1 and 14), otherwise it does not matter much. Also keep all the wiring as s...

The SuperCIC firmware is not capable of pulling such a feat :D You either have: - serious mistakes in the wiring - corrupted/wrong hex files - wrong fuse settings (they are included in the hex file) - defective PICs (unlikely because there are two mods with the same errors) However none of the above...

Can you take photos of your mods?
Also, does this happen with all games or just with carts equipped with a SuperCIC key?

Satellaview support is already implemented ;) However some games, most notably the Zelda Inishie no Sekiban series, cannot be played (without patching) because they rely on data that was downloaded from Satellite to RAM during the actual broadcasts. Oh, and S-RTC support is in. Time is supplied by t...

Interesting... EC (external clock) should be the correct setting.

So to clarify: It does not run at all on a non-modified console? Then there's a communication problem between the Host CIC and the cartridge CIC. The most likely causes are: - wiring problem (maybe Data0 and Data1 are swapped?) - fuses setting on the 12F629 (especially clock source) The hex file con...

Put the game with the 12F629 in an unmodded PAL console and switch it on. The CIC clone on the cartridge will switch to PAL. The game will probably not boot before you push reset but that's irrelevant. Afterwards the SuperCIC will detect the clone as a PAL CIC and switch to PAL accordingly. btw I'm ...

also, Skipp and Friends which I just tried - the .smc doesn't load all the level graphics for some reason ((most of the level is white and you don't know where the walls are)) The game doesn't initialize $2132 properly, leading to wrong layer1+2 colors on real hardware. It's not the PowerPak's faul...

It was brought to my attention that PowerPak users cannot enter the save menu anymore when using the SuperCIC lock because it hogs the reset button. Here's a test firmware that will reset the console for ~6 seconds when the reset button is tapped twice within 586ms. (Of course it's also still a full...

Don't yet, there is still hope!

In that case, would it be possible to support the MSU1 audio interface only? Just leave the data busy bit as always set.

Sure thing. Even compressed audio should be possible.
