I want to start running Trip World but I don't know which emulator I should be using for runs. Is there a specific one that's the only one allowed, or is there a couple to choose from?
you have a couple to choose from, we havent really had that many people play the game to really delve into which gameboy emulators you can't use... the only one that's not preferred throughout gameboy speedrunning is VBA, it's like the zsnes of gameboy.
most of the runs you see on the leaderboard here are on gambatte or bgb if they aren't played on supergameboy2/snes or gameboyplayer/gamecube or something, but i recently got a wii and my run is on wiimednafen. i recommend either that or gambatte
gl with learning trip world it's a really fun and addictive to grind :>
Doesn't matter as long as it is completely accurate to an actual GB/GBA. Accurate emulators are easier to find then inaccurate ones, especially for older systems like the GB, so don't stress too much about it.
Actually, by far the most common emulator used is VisualBoyAdvance, which as I stated earlier has really bad inaccuracies. Sticky post coming about changes to the leaderboard and stricter enforcements of which emulators you cannot use will be the topic, along with a link to a video comparison Blechy made showing the differences between known/accessible gameboy emulators.
BGB, Gambatte or Bizhawk are the ones which should be accurate. It's what's allowed in the LA/DX Community anyway :)
