Hello, fellow czech hackers!

Greetings from Brazil :-)

When I visited Brmlab a few years ago we hacked togeter a laser projector.

Recently I have been practicing a lot of reverse engineering and it is really fun. I started to contribute to the development of the MAME & MESS emulation projects and here is a list of the devices I've been working on writting emulators:

Now, remembering the fun experience we had with the laser projector, I wonder if anyone of you would be interested in dumping the ROM of the device in order to implement an emulator for it.

Since the laser controller board contains an EZUSB microcontroller, which basically consists of an 8051 + USB handling through hardware, I believe that the way to dump it would be by sniffing the firmware code sent during initialization through the USB port.

Anyone here interested in trying to acchieve that?

happy hacking,
