Darn. Now my best guess is that you patched Beta 2.2 on top of Beta 2.1. Because I'm compiling the entire ROM instead of hex editing, a lot of the code gets rearranged from patch to patch. I'm surprised it even works at all. Good to know you're keeping up the vids!
Hey, again. You should check out the bug list in the Maize thread. I just discovered (and fixed for the eventual complete version) a big bug in Copper Town. Don't talk to the guy standing on the rectangular path because if you lose the following battle (maybe if you win, too...), you'll be stuck in a glitchy map. On the other hand, if you have a Pokemon that can use Fly, you'll be able to escape the glitchy map. Remember, you can't use Fly until after you beat the Gym leader in Copper Town.
I heard your comments about Fraps not wanting to record Maize. Are you using VBA as the emulator? If so, maybe switching to a better emulator will do the trick. BGB is the best Game Boy emulator that exists, so I suggest using that instead when playing Gen 1 & 2 hacks. The VBA save file is perfectly compatible with BGB, too! Link:http://bgb.bircd.org/
Edit: The only drawback is that it doesn't have the "space bar hyperspeed" feature. You have to right-click and go to options to change the speed. In the framerate box, you enter a percent speedup. For example, if you enter "500" in the framerate box, it will run at 500% speed, or 5 times as fast as normal. Enter "0" to return to normal speed.
