goyuken c14e4239c4 Genesis VDP display. But not as slick as http://www.youtube.com/watch?v=Tsr-XtuKuSw 2014-02-19 22:26:33 +00:00
goyuken 343fbc7ae4 genesis: big savestate rework. all old savestates are invalid. saveram is now stored in savestate. non-megaCD savestates should be significantly smaller than before; megaCD savestates should be slightly larger. 2014-02-03 18:07:21 +00:00
goyuken 28c1347b75 genesis: only save the actual saveram (instead of an overly large file) in some cases with MD cart. disable automatic saveram (that didn't exist anyway) in most non-saveram carts. for mega CD, reduce size of EBRAM cart to 16KiB. it's still enough for a total of 3 Shining Force CD saves, so no complaining. 2014-02-03 04:04:53 +00:00
