So I took a look for differences between Project 64 and original hardware. I found that the later version of Project64 (2.3) creates lag whenever the menu is opened or closed, or when changing menu screens left and right. In battle, there isn't much difference, except that the emulator has a little bit of lag when mashing quickly between turns. I wasn't able to find any difference on the world map.

Gandair, you mentioned timing them side by side. Was that ever done? I'm trying to find your reasoning on disallowing emulators.

Incidentally, other N64 games (Super Mario 64, Ocarina of Time) allow Project64, but specifically an older version (1.6). This is because on some games, the later versions have less lag than original hardware, as you can see:

Weirdly, Aidyn Chronicles seems to be an exception to that -- the 2.3 version of Project64 creates lag that isn't found on original hardware, but the 1.6 version doesn't. From the limited testing I've done, it seems that running on 1.6 would match original hardware, while later versions pose a disadvantage.

Still waiting on a response here... Gandair? Considering the small size of the community for this game, and the comparative rarity of the cartridge vs. other N64 properties, seems silly to exclude people who can't afford to acquire original hardware, unless there's an unfair advantage that emulation poses.

Have you found anything?
