![]() I touched on this in the original thread. This is an edge case exposed by the game Micro Machines. I'm going to give NEStopia 2 points for this, since IRQ timing and cycle stealing are two different things. Rather than emulating the buffered sample fetch, it runs the DMC ahead a bit, then backtracks after the IRQ fires:Ĭpu.StealCycles( cpu.GetClock(cpu.IsWriteCycle(clock) ? 2 : 3) ) ĭma.address = 0x8000 | ((dma.address + 1U) & 0x7FFF) ![]() In this post, I am comparing Win versions of FCEUX 2.2.2 and NEStopia 1.40, which to my knowledge is the latest official release of each emu.ĭMC timing is very tricky, and a handful of Camerica games rely on reasonably strict DMC IRQ timing for split screen effects in some games, specifically Fire Hawk and the dreaded Mig-29 Soviet Fighter (one of the harder games to get working)īoth emus run the games correctly, but looking at the source, FCEUX cheeses it with a hack. But this might be fun and interesting nonetheless. This is far from an exhaustive list, and I am grossly oversimplifying by just assigning points to individual aspects. So did FCEUX catch up? Was I talking out of my ass? I decided to take a look into a lot of "gotchas" that plague NES emus which try to cut corners on accuracy. In that time, FCEUX has been in active development, while NEStopia has largely been idle. In my reply I made some bold claims and pretty much said "zomg NEStopia is the greatest thing ever omgomgomg", but I realized that opinion came largely from the state of the emulators ~7 years ago. bin/nestopia /usr/share/games/nes/kachikachi/CLV-P-NAARE/CLV-P-NAARE.Obscurumlux01 in another thread was curious about accuracy comparisons between FCEUX and NEStopia. bin/clover-kachikachi-wr /usr/share/games/nes/kachikachi/CLV-P-NAARE/CLV-P-NAARE.nes -guest-overscan-dimensions 0,0,9,3 -initial-fadein-durations 3,2 -volume 70 -enable-armet Your game should now run in Nestopia! Here's an example with Balloon Fight. Personally, I think it's easier just to hide the original games and add your own versions, but if you really want to play the originals in Nestopia, give this a try:Ĭlick on one of the original games in hakchi.Ĭhange the beginning of the command line to /bin/nestopiaĭelete all the other stuff at the end of the command line (everything after the rom name) I think this misconception is a combination of how using Retroarch with the original SNES Classic games is a bad idea + the fact that you can't use "select emulation core" with the original games on either system. Looks like someone already addressed how to use the core selector function in hakchi, so that's good.Īlso looks like people have mistakenly told you that you can't play the original 30 games in Nestopia. Even though I specifically avoided downloading the FCEUmm core, Retroarch still somehow opens my games in FCEUmm, which I find utterly baffling. ![]() I only have two mods installed: "Retroarch 181 Xtreme Ozone" and "Nestopia". "-nestopia" still opens the game in FCEUmm and "-core nestopia" crashes.Īs part of my troubleshooting, I erased all of my hmods and redownloaded them from the "new" (to me) KFMD mod hub. Various (possibly outdated) reddit posts have said to append "-nestopia" or "-core nestopia" to the command line. I can't find any official documentation saying to how to override default cores. I can use the global command line setting to append "-retroarch" so that every game opens in Retroarch, but it always uses the FCEUmm core, no matter what I do. Now, I can't seem to get that to work at all. I had it set up so that every game used the Retroarch Nestopia core. (I originally did over a year ago and can't remember exactly what I did.) I ended up have to reflash and reset the kernel to default settings, and now I'm trying to figure out how to get things back the way I want them. I was recently promped by the latest Hakchi version to update the kernel on my NES Classic, and it bricked.
