SA1 beta dragon, put back into game.

Lost cowgirl from casino.

To add the dragon yourself add this to SETSHT1S.BIN then add 10 to the first byte in the file.

If this mens we'll eventually see level hacks on the scale of the ones we have seen made for the Mega Drive games, I'm excited.

When I saw the title, I thought SA1 was the SNES SA1 chip...

Oh and also By editing the executable I made the game load different files than normal. I replaced were it said WINDYVLY1.ADX with SKYDECK1.ADX and now the games loads the Skydeck 1 music isntead of Windy Valley 1 music. I can change ingame text too. I changed TAILS to PENIS were it tells you "You can now play as TAILS" it now states "You can now play as PENIS" The word penis was just a test as it needs to be the same length of sentence.

And for refence the files in the main directory of the disk named "SONICADV_" are the files for online downloads. All they do is tell it to load different .html files, and icons.

Heres some debug text from the 1ST_READ.BIN
