For comparison, the SameBoy release process includes an automated regression test, letting each of several hundred Game Boy games run in fast forward for a few seconds and then alternating Start and A presses. To speed up test runs, it runs one emulator on each of 24 cores of a Mac. SameBoy automation results include a grid of screenshots.creaothceann wrote: ↑Sat Jun 03, 2023 2:20 am Supporting thousands of SNES titles is only doable in a few months/years because you just have to perfectly emulate a few components. IIRC back when bsnes/higan was developed, even testing if every single title reached the title screen took several hours/days.
Do any NES emulators have this sort of regression testing?
