Haze Megadrive Emu 0.11a
————————

Made the ‘Arcade’ bootleg of the Genesis version of Super Street Fighter 2 work.
This version takes coins and plays like an arcade game, (real credits, dips etc.)
but is based on the Japanese Genesis release of the game. Probably made either
because it was low-cost, or because nobody had found a way to bootleg CPS2 at the
time. (set name ssf2ghw )

Thanks to stephh for the help with this one.

This will be added to MAME one day, can’t give an ETA on when because I want to
be 100% happy with the code and compatibility of the MegadDive and SMS emulation
before I port it back.

Haze Megadrive Emu 0.09a
————————

Nothing major, I have no time these days.

Based on MAME 0.108u5

Improved protection emulation in some unlicensed carts

Lion King 3
Chinese Fighter 3
Top Fighter 2000
Super King Kong 99
King of Fighters 99
Pokemon Stadium
+ more

Some of these appear to work fine now (Lion King 3, Pokemon Stadium) others still have
issues (Chinese Fighter 3, Top Fighter 2000)

Hooked up backupram in several games [ShimaPong]

Changed way sprite masking works, fixes Mercs L1 boss (sound still problematic in this game tho)

Reorganized files a bit

*edit, fixed a stupid sprite bug in 0.09a, heres 0.10a*

Source+Binaries

This one seems to have some fairly good protection compared to the others, values read are stored for use later etc. instead of being compared directly. As you can see, it’s broken once you get ingame. In all other emus the title screen etc. is missing.

Another unlicensed Genesis game with some pretty evil banking protection + other protection on game events. There are still some problems with the AI (I think..) but it mostly works.

As an added bonus to this update I managed to get another one working, this only appears to have some banking protection. I was told it was called ‘Kaiju Kyougijo’ but it actually appears to be a game called ‘Pokemon Stadium’.. When will the madness stop?

Now to increase the lameness factor in this post 10x

Another unlicensed Genesis game.. this one with some odd banking protection as well as some kind of bit operation protection.

*edit fixed the last bit of protection, you can move now*

Super King King 99 uses the same protection
