I can remember a nice little graphics program called the Graphics Transformer that had some UN-COPYABLE protection, there was no way to make a duplicate with out using a capture cartridge, strange, once the program loaded, it never used the protected tracks again, it was also the Fastest loading program around, at least it stepped the head in the drive very very fast, maybe there was 50% sync %50 data but I never ran across this prg since then, Been looking to play with an original disk again, but no luck. Have any of you experienced this program ??

Ah, yes. Written by Joe Peter (of V-MAX fame w/Harald Seeley) and Scott M Blum (of Di-Sector fame).

I haven't run into the original yet, but it would be nice to have.

This followup is extremely late but...

I had (maybe still have?) a copy of Graphics Transformer and agree with you that it stepped the tracks faster than anything else (V-MAX, Rapidlock, etc). In the usenet discussion with Harald Seeley some years ago I asked him about that actually. Haven't analyzed the protection but I remember copying it successfully using Burst Nibbler.

The other weird thing about GT is that I had a 1541 that would NOT load it - would crash while loading, and it wasn't head alignment or anything. After much experimentation replacing the 6502 in the drive fixed it. I dunno what the loader code was doing, but this particular 6502 didn't like it (I'm guessing either illegal opcodes or maybe the 6502 in that drive was very old and didn't have the ROR instruction - according to "Programming the 6502" (Rodnay Zaks) old 6502s may not have ROR implemented).

I also remember Kracker Jax having a parameter for GT that require a capture cartridge (ISEPIC?) and then patching the captured program in memory. I guess maybe the program in memory used to communicate with the drive to see if the custom drive code was still there to foil snapshot type cartridges.

The problem with this crack was there was another part of the program (GEOS converter or something) that would subsequently load from disk so this technique wouldn't give you a 100% backup (unless of course you didn't mind the missing functionality).

But the real question is how come I can remember obscure 20 year old information like this but can never find my car keys?!

Nice to hear from you Nivek, I managed to grab your old web collection of cracks and such, was a nice place, any plans to re-implement and expand your old site ??

Thanks for the kind words! The site will be up, it's just that everything I do seems to take much longer than I think it will...
Not sure if I could ever begun to approach the fantastic quality of this (Pete's) site though!

Hey Jim, did you ever look into this title ?
part of the protection was written by Marty Franz
and possibly Herald Seely. I couldnt even copy it with Bnibbler, using V1.9 either 64 or 128 mode. I did manage to get a later version of GTransformer, and it appears to not have any protection whatsoever. It does not load as fast as the original protected version either!, maybe this was done for compatibility reasons with clone drives - Enhancer 2000/and like.

Does anyone have an original that they want to sell? This is one that I don't have, and would like to make a copier file for SuperCard+ as well as dump it using SuperCard Pro.

I got the Graphics Transformer. It copies with SuperCard+'s GCR Nibbler. It does use a custom format and interleave, so it stumbles on loading compared to the original unless you copy it with SuperCard+'s IHS. The disks were produced on TRACE or similar type of duplication system so the tracks are aligned and queued from the index hole.

He Jim, does the SC+ in a 1571 use the built in index sensor? or does it have to be a 1541 with the add-on hole sensor ?

Sorry, didn't see your response! You can use the 1571 disk drive. That is why I use most of the time for duplicating disks on a C64 because of the IHS and the fact that it will read/write weakbits.
