+5-11under Posted December 18, 2015 Share Posted December 18, 2015 (edited) See the link in my signature. I need to get the expansion port working. Hopefully another prototype during winter sometime. Video options would be available from me, otherwise the F18A. Maybe I need to change the board shape so it fits in a Jaguar shell.

TMS9918 for composite, TMS9928 for component/YPbPr, F18A for VGA. I haven't investigated TMS9929. V99x8 I don't think I'm too interested in. Is it compatible by default?

ApolloBoy Posted December 19, 2015 Share Posted December 19, 2015 V99x8 I don't think I'm too interested in. Is it compatible by default?The V9938 and V9958 aren't even pin compatible with the TMS chips so no. Quote Link to comment Share on other sites More sharing options...
matthew180 Posted December 21, 2015 Share Posted December 21, 2015 The V9938 and V9958 aren't even pin compatible with the TMS chips so no. Not to mention that the 9938/58 are only *software* compatible with the 9918A/28/29 for well behaved software, and will not work with some games. I know from experience during F18A development that there are CV games out there that abuse the VDP register selection bits, and on a VDP with an expanded register set (like the 9938/58 and F18A) that will cause problems. The CV is what exposed this to me during F18A testing and the reason I had to introduce the register-lock protection on the F18A. The 9938/58 do not have such register protection and would end up with corrupt register settings. Quote Link to comment Share on other sites More sharing options...
