Re: Legacy of the BBC Micro User magazine / Database Publications Ltd

I once wrote and had published a disk protection that relied on track 81 being readable! you can't even run this in an emulator, lol.

Re: Atic Atac: dodgy version in STH archive?

Hi Kevin It's sortof true, the Nightshade first decryptor does not have the cascade (either ADC &E01,X or EOR &E01,X where page &E is the loader) so because the game loads off tape without encryption it does allow for a possible hack here, by editing the mode change LOADING thing and saving that bac...

Re: new Nightshade hack idea

wow, Rich T-W is going to kill me for this, I just broke into the Galaforce protection with 42 bytes of software, no James Fidell emulation or breakpoints needed. I can't understand why I didn't see this before. The key is, the EOR &700,X instruction, and the fact that there's no attempt in the main...

Re: help required - sideways RAM emulator question

Thanks for the reply, I'm trying to write a software hack for the unspeakably hard Tapper decrypter (without emulating it!), and yes it has to be either sideways RAM or a ROM MOS modification.

help required - sideways RAM emulator question

hello, dang, I haven't posted in years! I'd like to know if it's possible to code (from the BASIC assembler) directly into sideways RAM, point the primary interrupt at your code and expect a BBC emulator to be able to run it. I realize that's a silly thing to ask, but it matters for a reason I'll re...

Re: Random game reviews!

lion, I'm sure people have told you before, but Zalaga doesn't run on a Master, most likely because it uses non-standard 6502 instructions to do things with the sprites. I think the Master uses up some of these values for its own slightly different processor?

Re: Starquake swears at you

Anyway I can't really think of a better way to do it than by hand, loop by loop. What did you have in mind? If I recall (and it is over 20 years ago) it had something to do with loading the encryption and running it directly in a different screen mode. It then bombed out after decoding the little l...
