Ripping can be quite pain, first you must find the track, second you must find the sound driver or exa´mine the track and write your own driver.
Anyway, my game, Glass Breaker MD is almost complete and I'm going to start writing BGM/SFX engine for it as soon as I learn z80 ASM.

No byte access, I used long word. I want my game to work in emulators too not only on real hardware (and that method works on real HW). I'll try NOPping. As far as I know, there is no rom/ram banking mechanisms in MD, if you want such thing you need to develope it on a cartridge. I believe that reg ...

The STATIC RAM on the cartridge. The cartridge works like this : any access below 10000h enables ROM and access above enables RAM, If you write something, the 68K pulls !LDSW (or !UDSW) low and that signal is used as WriteEnable on RAM. I did such thing with my pirate Sonic3 cartridge which doesn't ...

Problem with accessing SRAM
I'm writing a game for MD (Glass Braker MD) which is uses SRAM, but I have trouble accessing it. MOVE.L #$00010001, A0 ; load SRAM start addess MOVE.B #230, (A0) ; write byte MOVE.B (A0), D0 ; read byte Trouble is that the read byte is not 230 but 0. SRAM gets saved with 230 in *.SRM file. What need...

The VPP (12V programming voltage) pin is not on the cart slot, but it could be if you like (use some unused pin). I used a wire for that. I'm working on EPROM stuff as all EPROMs are not programmed the same way. There are lots of Flashes out there, if its industry standard and 5V it can be used with...

Its rough indeed...
It is rough, but it works !!! I dumped most my cartridges, messed with backup RAM on Sonic3 cart and
even BURNED an EPROM !!! Man, EPROMs program easy. I started to write the documentation and some instructions.

New home-made MD cartridge R/W device is born
On 2nd december is started to build a MD cartridge R/W device whis is 100% designed by me. Today (5th) I got it working correctly, I dumped my Sonic & Knuckles cartridge. It took 45 seconds and the result was a perfect bit accurate copy of the ROM image. If I ASM optimize my QB45 code (I love QB45) ...
