Last month, I took some time to help disasm the other bios of the SuperMagicDrive….
These bioses are coded for SMS Mode, in Z80
While I was in Z80, I got back on a projet I started (10?) years ago : Bomback disassembly.
In only some days, I finally finished it.
So bad I didn’t own IDA when I first started, it’s VERY helpful.
Do you know this guy ? 😉
He get back on my life recently…
It’s fun how my list on ‘best-stuff-of-my-youth’ is so short that I alway get back to the same thing year after year 😉
I found a very intersting software : Sprint Layout 5.0
It allows you to use a bitmap as reference to create your PCB layout….front and back sides!
I started yesterday:
I hope it will help me (and perhaps you!) to fix my Super Magic Drive
This time, I added mouse support !
This will not be included on SGDK until I’ll be able to test and verifiy my code  on real hardware.
Everything works on Fusion but, even if Fusion is the finest one,  it is an EMULATOR, not the real thing.
Then I hope to add Justifier then Menacer too!
Stef updated SGDK with a fixed sound driver…it was the culprit of my last bug on AnimLib
Great !
After the 6 buttons support, I added EA4Way and SegaTeamPlayer….
Now working on the mouse 😉
Stef updated sgdk again, mainly in sega.s boot code (grrr!!!)
So I checked if AnimLib will still work with it
It seems nothing broke…
WTF?!?
2/3 of the multitap games I analyzed share the same code…
I didn’t understand why until I added ‘Multitap – Sample IO program’ rom to my list of to-analyze-game.
I think they use a code shared by Sega, but what is fun is that they used it like this…including mouse detection / reading code 😉
The code is a little complex, because of the protocol to communicate with the MultiTap.
The EA4Way is far easier to handle !
I finally understood how the 6 buttons works….
Need to tune it a little more and add multiplayer support …
Yesterday, I played to Sin & Punishment 2 on Wii.
It was pretty cool and I tought “Wow! Space Harrier on steroids!”
Gameplay with the nunshuck is very weird, but fun 😉
You should try it if you don’t already.
