There are a lot of proprietary effects in printers that could not be replicated on a computer screen of the time. A printer from the 80:ies had both better resolution and in some cases color(s), so I think it is both cool and useful from a preservation perspective. Ideally we should be able to save a bitmap in the printer resolution rather than a screen dump.

For example I did something similar to this on my ZX81: http://www.hanssummers.com/mandelbrot/mandelbrotzx81.html

I dumped the ROM of the Wireless 60, a descendant of the Chintendo Vii, a cheap Chinese ripoff of the Wii. This system appears on the dumps wanted list!

https://www.dropbox.com/s/e5dpwr8jhas5h6b/wirels60.zip?dl=0

The ROM runs in Unununium, but without controls or sound:

Thanks! I'll see about getting it added this weekend when I have more free time, if someone doesn't add it before I do. smile

While trying to dump a keytronic 8048 microcontroler I tested my teensy 804x dumper with another similar 8048. I now have a Videopac G7400 French 1kb image that seems good (found string "quel jeu ?" inside). Was this rom already dumped and tested in MESS ? (it's different from G7400.bin and Jopac.bin found elsewhere).

my keytronic 8048 seems unfortunatly dead (does not go to read mode...)

AFAIK we have no French G7400 BIOS, so that would be nice to have. That's too bad about your Keytronic.

My dump is here but I'm not 100% sure it is functional since it fails if I replace g7400.bin with this file.

Remember to use the exact correct type of 8048 when dumping as 8748, DO NOT dump most 8048 chips as '8748', instead use '87c49' or similar, since eprom 8748 required a very high voltage for read mode which may blow up many 8048 chips, or permanently protect them by burning the /EA pin out!

plain 8748 uses 18 or 21VDC on /EA for read mode, while 87c49 uses 12v and seems quite a bit safer in that regard, i.e. dumping 8048 as 87c49. using a current-limiting resistor is also probably not a bad idea.

I do not dump with my eprom reader here (because my lpt willem is dead and usb willem do not support MCS48).
I dump with an avr and a 12V power supply on EA (with a resistor).
(in fact I also needed a real +5V power supply because my usb ports are more 4.7v than 5v... and this 8048H does not start at 4.7V)

Here is my patch to Unununium to add support for the Wireless 60:

MAME's u'nSP emulation is based on Unununium so that should be useful if someone gets to it before me. smile
