Soon after finishing MegaDrive, I have converted Game Boy and Game Boy Color carts to use internally the slot devices, and as a byproduct I found out that some “Collection” games, like Genjin Collection, Momotarou Collection, Mortal Kombat I & II and Super Chinese Land 1.2.3 were emulated as plain MBC1 even if they were in fact using an alternate switching mechanism. By fixing that, all of them now work fine in MESS and don’t freeze/reset anymore when a game is selected!
Also, I was able to add support for some pirate games which were not emulated before, like Rockman 8 (which might still have issues, given that enemies do not appear for whole sections of the levels… but it might just be the way it is originally, I don’t really know…)
and the raw dumps of Sintax chinese games (huge thanks go to Taizou, who reverse engineered the non-trivial protection for these!).
Some of these are quite interesting
others not so much, but still worth preservation to better represent the HK market
