Well, I think that it's not only me that has over the years taken a look under the hood of this game. I feel I only chopped off the tip of the iceberg with my findings, most notably:

a) 68030 incompatibility due to crap use of traps
b) Glitches on Falcon because he sets ST-low resolution in every raster change (lol!)

Anyone else ever saw the code and went "WTF?"? Please share your findings here, it should be a laugh Smiley

I remember that you can speed up the code by a significant percentage by removing the protection related code.

Instead of simply drawing in a back-buffer and swapping the screen address, the code actually draws in a temporary buffer, and then draw it on the back-buffer. When the protection triggers, the copy is reversed so you have the screen mirrored.

LOL. I read on another forum that he was pretty smug about performance and did everything possible to make it run on an ST. So maybe if I remove that bit of code it might run full frame on a TT (it's almost there atm Smiley)

Here is what you can add to the game to make it better. I released the full source code of the Shadow of the beast menu (Phaleon Gigademo), which happens to have two soundchip musics made by FFT:

Would be nice to finally have some music in this game Smiley

How about we release the patch loader source and all files and you add it ? Smiley
