OK, I tried this with several roms now an I think I'm doing something wrong. The first thing I noticed is that if I pad a rom it is broken afterwards (The menu is empty). I worked around that by putting multiple games into the rum until it reaches 2mb.

However, every game I try seems to be unplayable because of glitches. I tried Metroid II, Megman and Super Mario Land 2.

The only game that worked for me is Super Mario Land. It also had some glitches but I could play through the first levels. It is the same in mednafen.

Don't get me wrong, I'm heavily impressed that this is even possible. I just try to figure out what I'm doing wrong.

I ran it in mednafen with zelda and it seems to be working fine. I'm still speechless.
It seemed to run fine using the following command.
rominjector.exe gbemu.vb LegendOfZelda.gb
It seemed to pad it to 1024k automatically. I can't try it on actual hardware though so I won't be much help for that.

I have played Pokemon Red on my Virtual Boy, my life is now complete. Actually it works pretty damn good, despite not being able to heal at the Pokecenter (she won't give it back T_T) and the lack of saves.

I get graphical glitches too, I just figured it's just how it is being an emulator running on a freaking game console from 1995(I still can't believe this). Although those screenshots make it look like it works a lot better...Like for example in Mario Land the text at the top is all centered. On my VB the text at the top scrolls with the landscape as I run (along with some other graphical glitches)

So far the games that work pretty good are Mario Land 1 & 3, Pokemon Red, and Game & Watch 1&2. Games I tried that didn't work were Mario Land 2 & Bomberman 1&2 (work fine but bomberman and enemies are invisible)

Still, even in it's glitchy state this is extremely impressive. I can't believe MK managed to code something so ambitious for a ~20mhz cpu, and have it run at a decent speed. Seriously, amazing work. If the glitches are caused by something me or Thunderstruck have done and they aren't there for most...I just don't believe it, there's gotta be some caveat to this wizardry.

this is rather interesting and unexpected. MK, how far do you plan to take this? is this a 1-off release for the compo, and an experiment in having fun with coding?

Wow... great work! Did you write the emu from scratch, or did you base it off another emu? I had ported gnuboy many years ago, though the the performance was pretty aweful, and I never spent the time to optimize it. I'm quite impressed with what you've gotten this to do!
