carlsson Posted June 13, 2021 Share Posted June 13, 2021 (edited) I started the MinGW msys environment to get access to some better comparison tools. cmp counts to 3723 binary differences between the first and the last ROM you posted, despite they only differ in size by 1 byte. If it originally was built from the same bin + cfg, something really funky must have happened with bin2rom or uploading/downloading the ROM from AtariAge. I would assume the program crashes entirely if it was badly corrupted. But regardless, the last ROM is fine for me and probably everyone else.

+cmadruga Posted June 13, 2021 Author Share Posted June 13, 2021 (edited) Well, the funny thing is just downloaded that original rom and tested it. It worked on my side. Go figure. Could it be something with the "." in the file name? ? Edited June 13, 2021 by cmadruga Quote Link to comment Share on other sites More sharing options...
carlsson Posted June 13, 2021 Share Posted June 13, 2021 We're testing codes to Ghostbusters, but what we're really encountering are Gremlins? 2 Quote Link to comment Share on other sites More sharing options...
+cmadruga Posted June 13, 2021 Author Share Posted June 13, 2021 It's gotta be Gremlins! Either way, thanks for helping test the codes. 1 Quote Link to comment Share on other sites More sharing options...
+DZ-Jay Posted June 13, 2021 Share Posted June 13, 2021 I just caught up. So everything is working then? Yay! ?? Good job, guys! Quote Link to comment Share on other sites More sharing options...
+cmadruga Posted June 14, 2021 Author Share Posted June 14, 2021 (edited) I tweaked the code to work with empty account names. Also caught a bug that was preventing one of Wedlund Joakim's accounts to be validated. Now all of Carlsson's provided accounts pass the verification test. Does this feature make this port of GB the first cross platform game ever made for the Intellivision? ? One can play Ghostbusters on the C64, get an account number from there, then enter it on the Intellivision and continue playing. Then maybe take the Intellivision account number, bring it to the MSX and continue from there. Kind of neat to think about it. Here is the updated account verifier rom v0.2. prog.rom Edited June 14, 2021 by cmadruga 2 Quote Link to comment Share on other sites More sharing options...
carlsson Posted June 14, 2021 Share Posted June 14, 2021 I don't know which other games have level codes or similar that possibly could carry over, but you've made a great effort to get this to work. Quote Link to comment Share on other sites More sharing options...

carlsson Posted June 14, 2021 Share Posted June 14, 2021 Now I had to look up whether Hacker, also by Activision, had a similar code system but it does not seem to have one, only a general purpose login code to enter the game. Quote Link to comment Share on other sites More sharing options...

It looks like Survival Island from 1983 on the 2600 may have been the first use of a password save. But that game was not released on several platforms like GB did. So the cross-platform element was not there. Quote Link to comment Share on other sites More sharing options...
carlsson Posted June 14, 2021 Share Posted June 14, 2021 I found a few more codes if you have any doubt about your algorithm. http://www.commodorecheetah.co.uk/Cheats/000028.htm Quote Link to comment Share on other sites More sharing options...

Looks like the code is working well. I just tested those entries you provided, and the ones that don't work, did not work at Perifractic's either. So I'm assuming those account names/numbers are incorrect. Also, I'm not supporting the entry of those weird ones with numeric account names, neither those with letters as account numbers. Do the originals really support this stuff? I have to check. I don't think the accounts were supposed to be setup like that.

carlsson Posted June 14, 2021 Share Posted June 14, 2021 (edited) Yes. Codes like 12345 - 25393120 and LEFTY - LEFTY work on the original C64 version. However POKE and 2014,9 does not work. Also blank name + blank account number is not valid. I wonder if the other implementations support those or if it is by accident that in particular letter based account numbers work.
