El Destructo Posted January 15 Share Posted January 15 Revisiting the Atari 2600...my "pre-production special edition" Harmony cart #42 runs everything it's supposed to except these three Epyx titles; all crash out to no signal immediately after loading. At first I thought BIOS 1.05 might be to blame, but updating to BIOS 1.06 made no difference. ROM images run fine in Stella. BIOS and ROMs are the NTSC versions. The console is an NTSC light sixer. Any ideas as to what could be wrong? Quote Link to comment Share on other sites More sharing options...
El Destructo Posted January 15 Author Share Posted January 15 This poster had the same problem but says his Harmony plays the games fine on his 4-switch. Strange that this makes a difference! Quote Link to comment Share on other sites More sharing options...
El Destructo Posted January 17 Author Share Posted January 17 Replaced the TIA in my 6-switch with one from a 4-switch and now the Epyx games work on Harmony. Hope this helps others. Makes me wonder what's the difference between TIAs of different eras? Quote Link to comment Share on other sites More sharing options...
