Hereīs the Protocol of the "Broke up Doom Cartridge" It contains 16 MBit ROM,FX2 Chip,64 KByte SRAM without Battery Backup. If you would add a Battery and a Powerfaillogic , you can save with Doom also Yoshiīs Island!!! At the moment you have to start at the begin in case of the missing Saveoption! or you let your SNES on forever ( hehe ) In the next days i will put Yoshis Islandīs ram to 128 KByte bigger and will tell ya if it runs still! This would be normal!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Attention in case of the Position of the Adresses its nearly impossible to read that over a SWC from your SNES and copy it! So we canīt add a new position to the cartridge and write a converter for the files! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If someone could also copy that game (must be impossible) then he should contact us! We can (with that conclusion) plan a new Position!!! The 1st part would be to posite the Adress-Lines in the normal used rank of the MMU. The upcoming numbers till "A-15" speaks for the fact to count further. The Convertation in the right Format ist very simple. You have to split the File into 4Mbit blocks for example where you think the positions are okay! then there are 2 possibilities to put the cartridge together again! 00 Both bits are changed and 0 change does nothing 01 10 11 Both bits are changed and 1 change does nothing If someone could also read out the game (or for the begin the first 8 Hexbytes of every 64kbyte block) then he should contact us and we will write a Convert-Instruction... As Cartridge-Type appears $14!! This Code had also Vortex! We will check that later! So we maybe could verify the positions! (coz it got just 512 kbyte ROM) We still search Infos to program a FLASHCARD with a SWC to code! I could code since 12 Years 6502 and 8 years assembler (AGEL) ======================================================================= Cartridge Prints on DOOM: Copyright 1995 Nintendo SHVC-1CB0N7S-05 ------------------------- Parts of all Electronic things: (all SMD) U1 40 pol.
