This is the first one I've found with actual data in the secure hi-ROM area. Not sure what it's used for. The main ROM runs in EmuVT but with wrong colors and only in the top left corner of the screen. O_o


this one is doing the same trick as one of the other dumps we have where they're using 8bpp? gfx but the layout in rom is the same as the regular 4bpp gfx.

I was actually unable to find the additional planes in the case of the one we have, but good to know you have one using those modes if we need to investigate them further.

are you 100% sure of the dump size on this one? one thing I was wondering is if maybe the rom was meant to be twice the size, with the other 4bpp in the upper half of the rom or something..

the 'secure' area seems too small to be the rest of the graphics, infact the .hi rom is just a mirror of the last 0x10000 bytes of the main rom (identical content) and contains part of the submarine game.

*edit* I think it's actually just an alt 4bpp mode, not 8bpp

This one was dumped using a Xeltek programmer, plus the datasheet states that it's 32Mbit, so I'm certain of the size.

ok, good to know.

fairly sure it's just an alt 4bpp layout then.

I wonder if it uses a different palette format too, or if they just changed it for some other reason

also strange that they decided to store useless duplicate data in the secure area

it's closest to the 'Defender M2500P 120-in-1' anyway.

Here's another VG Pocket handheld, the VG Pocket Mini, model number VG-1500, with 30 games:

https://www.dropbox.com/s/ah2h5xoso0jfair/vgpmini.zip?dl=0

Runs in EmuVT, full screen but weird colors. The hi-ROM area on this one seems to be the same as the first 64K of the main ROM.

I got a nice obscure dot matrix printer with my Alphatronic PC ...

[Linked Image]

It's even badge engineered in a stylish mock celtic font ...

The thing runs on a D7811G MCU, and there are two ROMs under the Centronics plug in module.

That looks like an Epson MX-80 OEM. Compare to https://commons.wikimedia.org/wiki/File:Epson_MX-80.jpg

If so, having a full dump is pretty awesome smile

@RB Could you have a look if the printer's program ROM makes sense as it is or if the MCU needs to be dumped as well ... it has 4K internal ROM but can be used with external ROM as well.

btw it seems like things posted in this thread are not being properly archived, so links can die and roms can just get lost if things aren't processed immediately and a lot of stuff in here I don't think was processed at all. (Random bios dumps and devices etc.)

I strongly suggest anybody posting here ALSO sends a copy to mamedev, do not assume because you posted a link here that anybody actually downloaded it and kept it safe.

That is of course assuming things that are sent to mamedev are safely archived, so sending to both places is your best option, also if something doesn't get added, poke people about it, because anything not added still has the potential to be lost.

The team are only human, things can get missed, backlogged, or assumed to be somebody else's to deal with.

I'm posting this because I noticed several things on here that did not get transferred so existed only on the dropbox / sendspace links they were originally posted on (that won't last forever, especially providers like SendSpace) those are taken care of now (thanks Tafoid) but god knows how many others simply weren't processed.

Haze, I usually add photos or manuals to the dumps, so the archives get rather big which makes email cumbersome. If I add a file hosting link to the email, nothing is gained as opposed to posting in this thread.
How about granting regular contributors write access to an "incoming" , "upload" or even a personalized pure upload directory on the FTP instead?

It might be that such a setup already exists the problem is I guess knowing who is 'regular'

I agree posting things in public helps, my concern is that some of it is going to be lost before it get processed tho, so something does need to be done to help prevent that. There needs to be a clearer way of alerting people to 'this needs archiving'
