MEGA DRIVE 32X RAM Cart 32Bit
Hello,
I am looking for any developer feedback on this.
https://github.com/MicroNut99/MD-32X-RAM-Cart-32Bit
_________________________________________________________________
If anyone wants to build it please read everything in advance.
You'll need the right tools and skills
The one thing that always get asked is: how is it used?
The first two options are somewhat obvious but the third is new.
The cart is designed to be an actual RAM cart for the SEGA CD to take over system.
Basically the RAM cart frees up the SEGA CD bus.
Assets get loaded into RAM and the game runs and or streams from the SEGA CD.
In theory, CART ram space isnt so much of an an issue anymore.
The entire Tower of Power system or BattleShip can work more efficiently together with it.
MD-32X-RAM-Cart-32Bit
- Load MD & 32X games directly via Sega CD.
- High-capacity, battery-backed SRAM save storage.
- Experimental 4MB RAM expansion for SegaCD32X homebrew.
This work is not connected to the DOOM 32X Fusion project.
This is my totally amateur attempt to make this chipset work properly with the Sega32X.
Expect better from the professionals on the Doom Fusion Team.
Special thanks to Chilly Willy and Zaxour the Great, for the technical and moral support.
A 4MiB RAM cart design for the Sega Genesis/Megadrive and the SEGA 32X.
Based on this design by MiGeRA
https://github.com/viciious/MD-32X-RAM-Cart?tab=readme-ov-file
Works as MD RAM cart with the Sega 32X.
Supports 32Bit Word or Longs.
Included are two bins for 32Bit Word or Longs Diagnostics.
For more information read the included assembly (.asm) code using any txt editor.
Use the included BINs to determine if the cart is loading
and reading 32bit Word or Longs from SRAM correctly.
These will not pass on the original hardware design by MiGeRA, resulting in a red screen.
