Wilheim Posted October 7, 2020 Share Posted October 7, 2020 Well, I made a proof of concept on Altirra, putting TRIG3 ($D013) on GINTLK ($03FA) every frame. It worked fine. I just put an small VBI routine on $100, forcing GINTLK with TRIG3. If we find enough bytes on the ROM, we can add this routine and make it work. I will see it now. 2 Quote Link to comment Share on other sites More sharing options...

Thanks I looked into the cartridges. There is an illegal call into a keyboard routine. Maybe if we can generalize that call, we can fix it. Here's a beta that should do the trick. Please let me know if you find any bug. Monster Maze (1982)(Epyx) beta.bin 1 Quote Link to comment Share on other sites More sharing options...

FULS Posted October 7, 2020 Share Posted October 7, 2020 Thank you guys for all the work in converting these. I have one more request. Is there a Pool 400 cart that works on both the OsB and XL computers? I have these two images, one works on OsB only and the other XL only. On a Hex editor they look very similar. I'm thinking each one makes an illegal call into the OS. Pool 400 (OsB).bin Pool 400 (XL_XE).bin Thanks Quote Link to comment Share on other sites More sharing options...

Pool 400.zip 12.69 kB · 10 downloads Hi, I tried using Altirra in XL mode but couldn't get your Bin to work. Would you retry with XL and see. I might have my settings wrong. Also I couldn't get your Monster Maze to work in XL mode. Wilheim's (Post #52) works fine. Thanks Edited October 8, 2020 by FULS Quote Link to comment Share on other sites More sharing options...
larryleffaovell Posted October 9, 2020 Share Posted October 9, 2020 Hmm, you're right. Interesting. I'm doing all my tests with the atari800 emulator as I'm on Linux... The binary loads and shows the initial screen with both, 800 and XL/XE, but only when setting is 800 the game is working correctly and hangs on XL/XE. Tried the atari++ emulator and there XL/XE runs the binary but hangs at start and crashes with crashed at $a003 illegal opcode $02 when set as 800. Weired. Seems that something's borked with this cartridge or dump. Quote Link to comment Share on other sites More sharing options...

Wilheim Posted January 29, 2021 Share Posted January 29, 2021 Well, here's a patched version of Gorf. I had to make it as a 16k cart, because I put an additional VBI routine to patch the GINTLK check the XL/XE OS does. Let me know how it works.

I found it odd that it worked when set to XEGS mode so reset my settings and now it works on standard XL mode..This happens every so often, no clue as to why..Sorry for the false report..

_The Doctor__ Posted January 29, 2021 Share Posted January 29, 2021 (edited) Disk version saves game score etc. Cart does not. etc. (GORF) just one of the differences between the two Edited January 29, 2021 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...

Been waiting for this Rom to be fixed to work both in an 800 and XL/XE for many years. Now if I want, I can burn my own cartridge to be played in either computer.

Wrathchild Posted February 2, 2021 Share Posted February 2, 2021 Here's an 8K version, basically unpacking and repacking the original whilst introducing a patch to avoid overwriting GINTLK.
