classics Posted March 25, 2004 Share Posted March 25, 2004 For those wanting to make thier own Blaster cartridges, here is a flash rom programming image that will turn any 1mbit Atarimax flash cartridge into a Blaster cartridge. The original blaster ROM image posted only ran on 400/800 computers. This cart will run on any 48k 800, 800XL, 130XE, etc. Enjoy!

classics Posted March 25, 2004 Author Share Posted March 25, 2004 Try dis6502 for disassembling it. http://www.atarimax.com/dis6502/ Atari REALLY should have released this game! Quote Link to comment Share on other sites More sharing options...
Bryan Posted March 25, 2004 Share Posted March 25, 2004 Steve, what is the XL compatibility issue? I've noticed that it never returns from the routine at 81C7... still working on why. We must be clearing something the XL OS needs... -Bry 81C7: LDX #$1D ;loop counter LDA #$23 ;pointer to $2300 STA $1B LDA #$00 STA $1A TAY ;Clear Y 81D2: STA ($1A),Y INY BNE $81D2 ;Clear until Y=0 again INC $1B ;New page DEX ;Counter BNE $81D2 RTS Quote Link to comment Share on other sites More sharing options...

oesii Posted March 25, 2004 Share Posted March 25, 2004 Thanks for patching up and releasing the .exe version Steve, much easier to mirror it through APE and play on the real thing Has anyone noticed any big differences besides the copyright name between the 5200 and 8bit versions of Blaster? I still prefer to play games on my 8bit over my consoles, too many years of experiences I guess. Quote Link to comment Share on other sites More sharing options...
Goochman Posted March 25, 2004 Share Posted March 25, 2004 Here it is, give it a try Removed a protection @BAE9 as well. Steve Can someone suggest a Windows gz program or could someone post a zip version of the exe? Quote Link to comment Share on other sites More sharing options...
oesii Posted March 25, 2004 Share Posted March 25, 2004 I always use Winrar and never had any problems with .gz (I guess a linux standard). But here's the zip file of the Blaster.exe (sounds like that virus that went around ) blaster__cracked__xlxe_mod_.zip Quote Link to comment Share on other sites More sharing options...
Goochman Posted March 25, 2004 Share Posted March 25, 2004 Ack, Your zip file comes up empty? Not sure if its due to all the (, and such chars in the title? Quote Link to comment Share on other sites More sharing options...
oesii Posted March 25, 2004 Share Posted March 25, 2004 worked on my Windows machine, let me shorten the name and I'll repost in a second. Ok if this one doesn't work, then its all you blast.zip Quote Link to comment Share on other sites More sharing options...
Goochman Posted March 25, 2004 Share Posted March 25, 2004 worked on my Windows machine, let me shorten the name and I'll repost in a second. Ok if this one doesn't work, then its all you THis one worked great - thanks. Interesting game - needed a few more levels but in '84 this coulve been the successor to Star Raiders IMHO. They just needed to tweak the human graphics a bit though Quote Link to comment Share on other sites More sharing options...
oesii Posted March 25, 2004 Share Posted March 25, 2004 Heck, even my cat likes it, she's usually on top of the TV or my SC1224 monitor but for this game she's staring into the 3d graphics and wondering why Atari let this one slip away That and she likes to mock my high score which is only 127,000.

Wrathchild Posted March 25, 2004 Share Posted March 25, 2004 Can any one disassemble the game I like to get the source code. Here you go, just under an hours work with IDAPro :wink: It'll need work to get in to compile under something (CA65, TASM etc) but as it stands you can study from it (ROM entry point is $8000). One instruction I'm a bit dubious about is @$B219 : JMP (word_0_F0B2) However I'm yet to stick a debug point on the emulator to see if it gets run. Regards, Mark P.S. no I won't do Star Raiders, Pacman, Pole Position, Joust, Defender ... blast_v1.zip Quote Link to comment Share on other sites More sharing options...

deathtrappomegranate Posted March 26, 2004 Share Posted March 26, 2004 I always use Winrar and never had any problems with .gz (I guess a linux standard). I go with that. WinRAR is pretty cool. BTW, thanks to all contributors to this thread. It's been very instructive. Quote Link to comment Share on other sites More sharing options...

Saikyo Posted March 27, 2004 Share Posted March 27, 2004 Is there a way to convert it to 520ST programming code and is it possible to get it on a floppy that will actually work on a real 520ST? Quote Link to comment Share on other sites More sharing options...

Umm... no. This is an Atari 8-bit program. -Bry Quote Link to comment Share on other sites More sharing options...
