Alright drx, if you need to remember, you released several Jurassic Park Rampage Edition prototypes on February 23rd, 2008.

The earliest two of which will not run on any emulator. I'm not exactly sure what it is. I tried correcting the checksums and it didn't work.

After that I tried to see if the Rom Headers were the problem and that wasn't it either as I realized that the 0630 build (the earliest build that works.) had the same header as the 0620 and 0622 builds and it worked fine. Oddly enough, the headers for the 0620, 0622, and 0630 builds all say JAPAN GAME NAME when opened on the emulator. I opened the 0620 build in a hex editor and noticed that the header also had US GAME NAME a couple of lines down from it.

I'm just wondering if its not some issue with the roms themselves. I think that the programmers might have encountered some kind of problems when they compiled those two builds which caused it not to start. They could also just be a bad dumps or there's some kind of corruption happening with them. You see, when I load the 0620 and 0622 in an emulator, I get a black screen that never changes. The game just sits there.

If its not a problem with the roms then it might be a problem with how emulation for them is handled. Perhaps I should contact Steve Snake and give him copies of the roms to see if he thinks it might be an emulation issue rather than an issue with the rom.

For me, it is essential that those betas work. The 0630 beta had tons of little graphical eye candy different from the final. Including exploding people and dinosaur animations that were cut from the final. The Triceratops' exploding animation was especially amusing. 

These two betas have got to have more awesome things on them. That's one of the reasons I'm so determined to get them working.
