Sleep/Savestates/Memories support? about openfpga-snes HOT 8 CLOSED

For me, save states / sleep mode is essential for SNES. Which is why my analogue pocket is collecting dust...

Hoping it will happen due to competition in the market (I see it on the horizon)

Unlike software emulators, hardware emulators (what we're running on FPGAs) have a significantly higher complexity and must keep track of much more information. Consequently, retroactively adding save states to a core that was not planned around it is a very difficult task (and it's still not easy if you have planned for it).

The person most knowledgeable about the core, srg320_, has previously stated that he has no interest in adding save states. Unless someone very skilled and dedicated decides to do it, it isn't going to happen. It's honestly probably more likely that someone else starts a SNES core from scratch with the idea of including save states.

Sleep requires save states, which won't be coming to the SNES core. The only third party core currently available with save states is my NES core.

Just wondering why save states won't be coming to this SNES core? Is that the owner doesn't care, or that it's incredibly difficult (more difficult than NES)?

Thanks for the response! I was wondering whether this was a save state thing. I've linked this issue (see above) in upstream in hopes that it'll get resolved someday. :)

Thanks for the quick reply. I hear what you're saying, but why does the NES core have save states then?

from openfpga-snes.

Someone (RobertPeip, and a few people helping him, I think) was dedicated enough to add them. Other than mappers (of which only some are supported for save states), the NES is significantly less complicated than SNES, and the hardware is more understood by more people.

Fair enough. Really appreciate your responses. Hopefully, my questions didn't come off as frustration pointed in your direction. Thanks, and have a good day sir!
