Not sure if this helps but i get pretty simular behavior between sd2snes and mister my sd2snes is on the most recent firmware - i always just figured it was how this game was on the snes as im used to playing it on my amigas. Check out the video a few posts up at https://youtu.be/Tzc3e-W6z78 . Are enemies bothering to shoot at you from range with ...

Thank you so much Dufus!

edit: Just loaded up E1M1 on Ultra-Violence in bsnes and it seems identical to how it behaves on your flash cart & SNES setup.

What boggles my mind is that the poster themself can’t help repeatedly pointing out the very unique development history and rare enhancement chip used by the game in question, yet can’t seem to fathom how it could possibly be one of few releases remaining that has accuracy issues.

Thanks. Surely a better use of my time than what this has degenerated into. I will do so later today.

Thanks again. I've outlined very obvious inaccuracies three times now with increasing specificity. I guess there's not much else I can do.

And if you think ao486 - which is still rather far from mature - is somewhat more accurate just because it's FPGA...well, :) The core isn't 100% but with the fragmented nature of PC hardware even back then, you have to take the middle ground approach. But I digress, even if the 486 core not 100% such a old DOS game like Doom runs fine. And when th...

akeley, FoxbatStargazer: Thanks! I was starting to feel like I was taking crazy pills.

If you want to compare for 100% accuracy, forget PC Emulation. You need to find someone with the actual game cart. Yes no one came up with a real cart to compare. But it's been shown and documented that the Enemy AI is already off on the SNES version of Doom. It been already established that whole portions of the enemy script is turned off or left...

It possible that the issues stems from how cut down the SNES port of Doom was. It's one of the few ports of Doom not to use the Doom Engine. It used a custom Game Engine called the Reality engine and it was done by one man Randy Linden Floor and celling textures were removed as well as particle effects to save on the limited Ram and the SNES own b...

Yes I was comparing SNES Doom on Mister vs on an emulator. The same rom even. Relieved to see someone saw the same behavior. I thought it must have something to do with Super FX2 implementation. Yoshi’s Island seems fine to me as well, but it seems Doom may utilize it in a less conventional way. edit: Yeah we’re not talking about subtle differences...

Replayed the whole game in bsnes as a comparison. I couldn't tell any real difference as far as how the game runs and handles inputs. All the inaccuracies seem to come down to how enemies are handled. To elaborate on the inaccuracies when playing on MiSTer: Enemies almost never attack from range and rarely melee, when they should attack constantly....

Enemy behavior in SNES Doom seems to be borked. Is this an issue with Super FX 2 accuracy? Or something else? Embarrassed to say I played through all three episodes today… constantly thinking “this can’t be right,” but having no frame of reference for this port. Checking out people’s youtube playthroughs and playing a bit in retroarch confirmed the...
