definitely has 4bpp tiles, maybe even 8bpp on these models (that alone could be why EmuVT can't run them?)

I've heard nothing but crappy looped samples for sound, so might just be some DAC or crap sample playback hardware.

some of the more recent ones look like they might add more scrolling layers.

the thing I own (which I'm guessing is some version of the same tech) also has a bunch of NES games on it, so it is somewhat backwards compatible too.

also, is it still true that only EmuVT, a closed source hack of Nester, runs any of these? with all the NES emus out there nobody else has bothered? or is that info out of date.

A big lot of Gundam RX-78 stuff just popped up, we are trying to do a collective effort to buy it and then dump everything so if anyone is interested on chipping in please let me know. This will undoubtedly be pretty expensive (probably $500+) already have 3 backers, but won't be enough and any extra help will be appreciated. There are around 2 days left so not much time either.

This is one system that doesn't have anything preserved yet other than a basic cart and due to its rarity it's very unlikely that there will be another possibility of buying so many games at one go (This is around 10 games), it does come with the actual machine which will make the whole thing much more expensive of course, but it will be worthwhile as I haven't seem anything RX-78 related to appear since quite some time.

They do appear, but are quite expensive. For example, Perfect Mahjong is available right now, but it costs 6500 yen.

nope that's not going to happen unfortunately.

We didn't win the auction, as usual some deep pocket Japanese collector bought the whole lot for around $1,500... and there goes a unique chance on preserving this system.

I'm aware, but that's overpriced for that particular game also it's not clear if it's boxed or not (if it's boxed it won't be too bad). We did buy the Golf game so at least that one should get dumped soonish.

I now have a dump of the Flash ROM from the sequel to the Wireless 60, the Wireless Air 60 (this one also appears on the MESS wanted dumps list):

https://www.dropbox.com/s/kcseun7qgexi0mc/wlsair60.zip?dl=0

The ROM is NAND Flash, and there is a RAM chip on board as well, so the Flash ROM contents must be copied into RAM somehow, which means a BIOS hiding under an epoxy blob. frown

I noticed the string 'PGandnandn' at the beginning; in reversed-endianness, this is 'GPnandnand'; GP would be General Plus, which is Sunplus by another name. (I'm sure the dump has the correct endianness judging by the other interesting strings I found, like 'SP_ToneMaker' and 'GLB_GP-FS1_0405L_SPU_1.0.2.3'.)

A lot of newer MCUs can boot off of flash; they have a bit of logic to copy some fixed amount to RAM and boot. So there may not necessarily be a BIOS.

"GPnandnand" as a required signature appears to be referenced right here, in page 19 of a GeneralPlus document;

somewhere else entirely
Yeah, definitely not a bios but an internal on-die bootstrap rom instead. Wonder if it's trojanable.

OG.

This one gave me lots of trouble: ripped off pads meant soldering to traces, poor contact with the adapter meant having to apply pressure with a vice (would have been easier with a C-clamp but I don't have one), loads of errors meant making dozens of dumps, only being able to find one of these things (besides one on Amazon from a seller with a 0% rating) meant having to work with what I had. But I got it: the dreamGEAR Wireless Motion Control with 130 games, model DGUN-2500. This is the one that includes Curly Monkey 2. smile
