Hmh, doesn't that mean it always responds above 400000, what could cause problems with SegaCD?

If you look at the docs for the hardware (he does post those along with much of the source for the OS and drivers), it's not ALWAYS responding that way, but only when in certain operating modes.

Sounds good then.
Edit: where are the docs, only given when you buy it?

Be aware that CD hardware is accessible at 400000-7fffff when !CART is grounded.

They're on his web site, and anyone can download them.

If you look at the Everdrive-MD page, you'll find that link and many more.

I was talking about Masyanaya's new cart HardWareMan posted about.

According KRIKzz doc his hardware also stopped touching 400000-7fffff in later firmwares, because of CD I assume.

Sorry, it wasn't clear seeing as you asked for them in the middle of my talking about the Everdrive-MD. :D

But yes, I'd like to see some info on the other cart, too. Feature lists are usually not a great source of info.

This card support 6 different memory maps. I assume that 5 standard in 4MByte area (with or without SRAM/EEPROM) and one in extra area $400000+. I already requested programmers manual for hardware, when I get it, I will check this info.
