This makes me wonder if Nintendo actually went all the way with the "faithful reproduction" in this one, including its innards.

It seems to be quite faithful, considering they got some of the original team that made the original to work on the reproduction.

I'm pretty sure the super mario bros mini classic has a bug on the later level (spinning fire barriers) that can crash the game. Certainly don't recall that in the original.

I've been busier than I thought, and it's likely to continue through the end of the month. But then it looks like I'm pretty open through the end of the year.

I've decapped, photographed, whinked, and photographed all the chips from the stuff I've bought and Hap sent me, but I need to composite the pics, transcribe the bits, and document the hardware. Incog sent me a big package of PCBs with blobs, too.

The only one I've finished up so far is DataMan: www.seanriddle.com/tms1980.html I did all the work on that then looked at the patent- it's got the schematic, VFD connections, and source and object code! Oh, well, I verified that the unit Hap sent matched the patent.

Kevin- Incog sent me a couple of NEC chips- a 42-DIP D774C Cassette Vision board marked with what Google Translate tells me is "TV Vader & Yosaku", and an 80-QFP D75316GF from Barcode Blitter. Let me know if you want me to send those to you to dump electronically.

Oh, do we finally know what the D774C is and how to dump it electronically? Guru had me looking for a while...

hap and I speculated that the D774C is a special ucom4 mcu plus built in simple video display ASIC thing. Possibly a 128x128 3bpp framebuffer and a composite ntsc driver?

Great smile having the patent with commented src code for the Dataman will be very useful when I add it to MAME.

I'm not spending much time coding these days: got a new PC recently and am catching up on some games I wasn't able to run smoothly before. I completed Arkham Asylum today. Up next is Arkham City and if I'm not fed up with the batham by then, Arkham Knight :P

Arkham Knight was great, I'm all bathammed out.

I added support for TMS1980 to the TMS1xxx core. TI DataMan is emulated and works.

Anyone know how to get ahold of Kevin these days? He's not responding to PMs and I _really_ need to get my games back from him soon...
