Hi,
this is actually a fail project of mine. I posted here since it is an idea after all. Many arcade games still uses cdrom/later dvdrom drives. And as arcade tech, i faced with a challenge when the cdroms died and no where cheap to get replacement.
I might get embarrassment from posting this, but i really want to make this one works. Maybe someone with more experience can give some hint.
the idea is just replace the cdrom drive and the disc, with hardware emulator with sdcard as data medium.
i used stmf4 as main microcontroller, which i thought, can accomodate the ide bus communication. later, i found, anything i did with the coding, was very far from accommodating the task file register responses. it's been several months since last i put this thing suspended.
asking around in electronics forum, suggesting using fpga, which is completely new to me, and might took years to accomplish. ah well, i felt hopeless about this.
