What I want to discuss here is another aspect of the problem, whether the ROM information of the save function fixed version needs to be or can be included in the DOM.
Although the cartridge released by Limited Run Games itself is a fram chip which means SRAM save type, it can be seen from the information inside the ROM that the original save type is EEPROM_V122, and the specific size is EEPROM 4Kbit (/512Byte). At the same time, after comparison, the save hex value of the ROM is exactly the same as the value of other EEPROM_V122 games after the folk tool GBA Tool Advance applied sram-patch on them.
That is, the rom itself should be the SDK function of EEPROM_V122, designed to be burned on a cartridge with a save chip of EEPROM 4Kbit (/512Byte) and a rom chip of 16MB. However, in order to burn the rom on a FRAM cartridge, the publisher used GBA Tool Advance to apply the sram-patch.
So should we include relevant information for the original design rom that has removed the folk sram patch and restored the EEPROM SDK function or not?
(An eeprom save fixed patch has been released on gbatemp. Due to the rules, it is inconvenient to attach it here. You can go to gbatemp and search for it. I only list its info here.)
