Wrathchild Posted January 1, 2008 Share Posted January 1, 2008 (first 2008 posting so...) Happy New Year! My repsonse would be 'probably not impossible - but quite a bit of work', which actually equates to 'not likely'. Check out the posts on this thread: Atarimax forum posting A summary is that the code protection in there is too clever Regards, Mark Quote Link to comment Share on other sites More sharing options...

I would need to add a PAL mod to my XEGS but that won't do me any good I don't have a TV that works in PAL. Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted January 1, 2008 Share Posted January 1, 2008 Tape version uses bank switching (i.e. D301) and also has some sort of data scrambling routine (or is it encryption)...which is why you can't do anything with it (back in the day, i tried to convert the tape version to a binary file) Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 2, 2008 Share Posted January 2, 2008 The easiest way would be to just have a loader which uses a "Save State" file from the emulator. But, as Mark said, if the thing has subversive code snippets that checks the PAL status and whether sections of code have been modified then it becomes a much harder job.

walter_J64bit Posted January 3, 2008 Author Share Posted January 3, 2008 Hmmm, how bout a conversion from the 5200? Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 3, 2008 Share Posted January 3, 2008 Was an NTSC version done at all on tape or disk? Conversion from the 5200 or A8 cart version might not sound so crazy if the game protection is what it's cracked up to be. But, that might necessitate 128K RAM, which kind of limits who could use it. I can remember someone lending me this game on tape - I'll have to check my 5.25 collection and see if I have a disk version. Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 3, 2008 Share Posted January 3, 2008 Seems the binary version I have is a "Hack-Atari" release (crack). It shows the scrolling load screen while loading, but corrupts then crashes if you switch to NTSC. Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted January 3, 2008 Share Posted January 3, 2008 Was the PAL detectioin code part of the BBSB tape loader...If it was you might be able to hack it out (if you're into 6502'ng) If it was part of the 2 additional data blocks that are loaded after the tape loader (the first one force loads into page Cxxx, going by memory and the second one loads in at either page 04xx or page 06xx....the second data block i think is the main game code) then you'll have no chance of moddy'ng the prog as the loader has some data encryption or scrambling routine...again only going by memory) Converting the 52 version to the A8 is going to present it's own problems, what with the different mem locations and potentially different rom bankswitching techniques, I think you'd be better of trying to hack the A8 cart version (but only if it doesn't have the same protection system as per the tape version) If memory recalls, all the Firebird (UK) A8 tape games use a very similar data scrambling technique as does International Karate (Tape version) Quote Link to comment Share on other sites More sharing options...
Wrathchild Posted January 3, 2008 Share Posted January 3, 2008 No, the detections are made as the code is being run - bits from the PAL/NTSC register are masked against data (IIRC as level data is extracted) and so although I could 'fix' that, some other routines must be using checksums on the areas that 'could be' changed by a hacker and then used as a mask themselves, so therefore the data/code corruption stems from there.

Shawn Jefferson Posted January 4, 2008 Share Posted January 4, 2008 I don't really understand why though... isn't there already NTSC versions of this around that can be played ? Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted January 4, 2008 Share Posted January 4, 2008 I don't really understand why though... isn't there already NTSC versions of this around that can be played ? I thought so. I've got a .xex and .atr here that seem to work. Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 4, 2008 Share Posted January 4, 2008 If so, can you upload one. I've downloaded and tried at least 3 versions, and the one I have on floppy. None of them work in NTSC on the emulator. Quote Link to comment Share on other sites More sharing options...

Shawn Jefferson Posted January 4, 2008 Share Posted January 4, 2008 and there's one here: http://www.atarimax.com/flashcart/forum/vi...ighlight=bounty scroll down the thread and find bbfix3.zip At least it runs for me with 60hz and 128k RAM, which seems to cause other versions to crash. I'm sure the version posted by Remo is the same, or similiar. Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 4, 2008 Share Posted January 4, 2008 Yes, I tried Remo's one and it seems fine. Binary load file, and fully tolerant of changing video systems at any time. Checked up to Level 3 (and might I add it's a bitch to play with a PS1 controller). Quote Link to comment Share on other sites More sharing options...

www.atarimania.com Posted January 8, 2008 Share Posted January 8, 2008 Does anybody have the super, super rare tape version released in the Netherlands by Aackosoft? As an original that goes without saying. -- Atari Frog http://www.atarimania.com Quote Link to comment Share on other sites More sharing options...
Shawn Jefferson Posted January 9, 2008 Share Posted January 9, 2008 (edited) I've just tried this one my XEGS won't run it I'm going to try the other file and see what it does. I believe the one on Steve's site has been fixed to run on the XEGS. Did you try it out ? It's the bbfix3.zip file you want.

Shannon Posted January 10, 2008 Share Posted January 10, 2008 What is the sound supposed to be like in this game? It sounds nothing like the original. Oh, and it doesn't have the settings screen like the 5200 (number of lives), or am I missing something? Quote Link to comment Share on other sites More sharing options...
