Wizzard Posted June 17, 2021 Share Posted June 17, 2021 This happens on my RGB modded Atari Jr PAL, both NTSC and PAL version of game. Maybe just another synchronization issue like in Thunderground. VID_20210616_230917.mp4 Link to comment Share on other sites More sharing options...
Thomas Jentzsch Posted June 17, 2021 Share Posted June 17, 2021 Is it getting stable after a while? Link to comment Share on other sites More sharing options...
Wizzard Posted June 17, 2021 Author Share Posted June 17, 2021 No, I am mainly using HSC version, but I think it is the same in all versions. Like some Atari Jr timing issue. Link to comment Share on other sites More sharing options...
+Al_Nafuur Posted June 17, 2021 Share Posted June 17, 2021 have you tested the none HSC version? Link to comment Share on other sites More sharing options...
Fierodoug5 Posted June 17, 2021 Share Posted June 17, 2021 That game has issues on some 2600jr consoles. My real cart version of spider fighter does the same thing on my NTSC 2600 Jr. 1 Link to comment Share on other sites More sharing options...
Wizzard Posted June 17, 2021 Author Share Posted June 17, 2021 Yes, also non HSC version have this problem, just NTSC version is not so bad, but the problem is still there. Ok, so it is a common ROM problem. Link to comment Share on other sites More sharing options...
Omegamatrix Posted June 19, 2021 Share Posted June 19, 2021 I just read this and applied a fix to the HSC roms. It looks like the root cause is Spider Fighter is hitting HMOVE ending on cycle 67 (12 cycles too early), and your console does not like that. 1 Link to comment Share on other sites More sharing options...

First I thought that it was fixed, but later the problem happened again, after a few minutes of playing, both on NTSC and PAL version. 1 Link to comment Share on other sites More sharing options...
Omegamatrix Posted July 1, 2021 Share Posted July 1, 2021 Just saw this. It's the same problem and I don't know what I did but the roms I posted early were still off for timing. I just uploaded new roms. Please try it now as it should be fixed. Link to comment Share on other sites More sharing options...
Wizzard Posted July 1, 2021 Author Share Posted July 1, 2021 (edited) OK, it is completely fixed, I played a couple of minutes both NTSC and PAL game HSC and no graphics issue happened. Thank you very much. edit: would it be possible also to fix non HSC versions? Edited July 1, 2021 by Wizzard Link to comment Share on other sites More sharing options...
