Hello! I know this thread is old, But im wanting to adventure on this, so i bought a super cheap machine, gifted with colacao in spain what looks like is based on same machines here, also i found this post through a similar arcade machine hacking video. I want to share some screenshots of inside and you can tell me if is really worth to try something, if thats the case, i going to buy the tools mentioned in other coments (USB CH341A EEPROM BIOS Flasher), but i want to stay sure i get all i need to start trying to hack this machine, i never made a flash like this but i want to learn and i want to hack this machine if is possible, and for sure the experience can help me learning to flash other devices, so im greatefull of any help can have here. And the last thing, you know better than me what i need, but looking for eeprom bios flasher i readed the guy has with 3.3v modifier, but i want to evade solder if is possible, because i dont have experience on it, so looking this can be able to use?
https://es.aliexpress.com/item/1005006440681067.html this says have a 3.3/5.0v power output, what i think saves to make the mod to 3.3v
PD: The unreadable chip says: M36L0T705 0T3ZAQ W0 99B6A VS MYS 99 933 (i discovered through google searching the logo in the chip is the ST Microelectronics logo)
128Mbit (Multiple Bank / Multi-Level / Burst) Flash Memory 32Mbit (2M x16) PSRAM (Apparently)
i found this datasheet where is listed the chip (Last in the list M36L0T7050T3ZAQ)
https://elcodis.com/parts/6260804/M36L0T7050.html and has a manual of it, obviously with my knowledge i dont understand nothing but i think can be usefull to know what machine is this.
PD2: The nesmaker link is dead, the v1.8.1 link is not working so i have here a found alternative link if someone is looking between.
