Does anyone have a schematic of a GBAMP CF? I want to build one with an HDD.

Cut a hole in the red plastic large enough to insert a type-II CF card, and insert a Hitachi Microdrive hard disk. Voila, a GBA Movie Player with a hard drive.
Using a regular ATA hard drive may be more difficult. Straight ATA is a 5.0 volt signal standard, while CompactFlash allows the host to use either 3.3 volts or 5.0 volts. The GBA slot provides only 3.3 volts.

What about the usb powered usb hard-drives. But up to a certain point it's cheaper using flash memory!

USB is also 5.0 volts, and it would need a USB host controller chip on the adapter and a separate power source so that it doesn't run down the DS's battery in two hours. Remember that the PSP's battery life issues are partly due to its rotating UMD media.

Battery life was tested playing movies from the UMD and from the memory stick, and the difference was only about half an hour. The PSP just eats a lot of power, period.

Yeah, not paying attention:
SCHEMATICS of a GBAMP. Not how to add a microdrive. I want to build one with an IDE port instead of a CF Port. The just use a battery for the power. I just want to know what Surface Mount components and the IC's are.

A CompactFlash interface for the GBA Game Pak slot or DS SLOT-2 can be downloaded from DarkFader.net DS. A GBA Movie Player is just a GBA cart (see reinerziegler.com for details) where address bit A23 is used as a chip select between a NOR flash memory and such a CF interface.

Why didn't anyone just send him to Natrium42's IDE to NDS Connection? It seems this is exactly what he wants to do, no?

Not asking for how to adapt, know how to do that, but does that Darkfader one work well with GBAMP compatible NDS Programs or what?
#117743 - chishm - Wed Feb 07, 2007 2:02 am
If you wire it up correctly, then yes. It is only a GBA bus <-> IDE adapter though, so you won't be able to boot from it directly. In that sense, it's more like the Max Media Dock. Booting requires a ROM and some logic to switch between ROM and IDE.

So if I used something like DSiPod or Moonshell on my M3Simply, it would load the files properly, but I can't just use a passcard to start it right?

Exaclty. FlashMe won't work either, but you could code your own custom firmware to work in conjunction with the IDE adapter.
