Hello,
I am currently trying to find a way to backup photos from my old GB Camera to my PC. I figured I could use the EDGB to load the GB Camera ROM then use a second GB(C/A) and a Link cable to transfer over the photos from the GB Camera to the EDGB, then grab the savegame from the EDGB folder and drop it into a programm called GB Camera Dump.
I've actually managed to do that by setting the save RAM to YES manualy after l load the Camera ROM. However, the GB Camera has 128Kbyte (16x8kbyte) of SRAM, EDGB only allows us to allocate 32kbyte.
The result is that the Gameboy Camera ROM will not work correctly and sending photos over to the EDGB might send photos into nirvana instead of the actual SRAM. I've found that apparently the last 6 photos i transfer over are actually saved. I fell like this is somewhat risky, as we could potentially loose precious photos that we might not have saved anywhere else (see
http://krikzz.com/forum/index.php?topic=2865.0 for an example), luckily I am doing my experiments on a secondary, non-vital GB Camera.
Now my question: is the 32Kbyte SRAM Limit an actual hardware limit (i.e. there's only 32kbyte of SRAM actually on the board) or if it is a software limit that was set because it was thought a bigger SRAM was not needed? If It's the latter, can we expect 128Kbyte SRAM Support in a future OS Update?
Regards
Sascha
EDIT: From the looks of it, there's actually a 1024Kbit RAM Chip attached to the board, which would equal the needed 128Kbyte. Is the chip solely used as SRAM or does it serve another purpose? I assume the EDGB OS itself uses part of that for keeping settings?
