I'm quite excited about the Pied Piper. Using the ROMs and available schematics, I've rather hastily constructed a preliminary driver that gets to the point where the system beeps and prints "Insert system diskette in Drive."

Somebody has just uploaded the PC booter games from Demonlord's site over here: https://www.zonadepruebas.com/viewtopic.php?f=59&t=8717&start=30According to the ibm5150 softlist, some of these had been MIA since the site went down.

And here's the TeraDrive's TMSS ROM for its Mega Drive side, dumped by armadylo: I may have just dumped the TeraDrive TMSS
also the MD side does indeed have a 10MHz mode
if you are running a game with SEGA TERA68K in the header instead of SEGA MEGA DRIVE or SEGA GENESIS , the MD/PC switch is instead a 7.67MHz/10MHz overclock switch essentially Well, I'm HOPING this is being dumped correctly, as there's hardly any way to properly test it.
Because running a MD ROM with a SEGA TERA286 header actually allows you to also run something like Puzzle Construction with a cartridge inserted (Normally, it will just not boot into it if there's a cartridge inserted), TMSS is still technically in memory at PC memory address space: CF000-CFFFF (depending on memory configuration on PC side) One thing that is right at least, now that I'm reading the header, is that the header shows the ROM size as being 0FFF bytes large... which is exactly the amount I was able to dump  So maybe it is right... I can't 100% confirm this is accurate, but it may be: Also: reminds me, the japanese mega drive systems have a different tmss than the us genesis systems (either the boot rom is different or they removed the "you have to write SEGA to enable the vdp" feature from the system)
this is because some early japanese games didn't write SEGA to the vdp Not sure if that one has been dumped already.

Regarding the PC booter demonlord releases, note that even though there's a "cracked or patched" folder, there's also some cracked/tampered dumps outside of it, such as the Alleycat image that's currently in MAME: ![[Linked Image from i.imgur.com]](https://i.imgur.com/R2gESw8.png) And there's also this note inside said folder: Look in TDC for more cracked image files in td0 or img format.
Look for "game name (year)(publisher) [genre].img.zip"
^^^^
.img.zip is used to denote these are disk images waiting to get converted to dos .COM/.EXE files.
Once a DOS conversion is created, the cracked disk image file will get moved here.Fortunately, most of them have a "FILE_ID.DIZ" which describes which are the cracked files and which are the originals. For example: Digger (teledisk+CP2+cracked image) List of games inside that "cracked or patched" folder which are currently in MAME: -decathln -ghostbst -mastodon -tapper -tapperc

I have looked at a couple of games where I have flux-level dumps of the originals to compare, and I get the impression that some of those TD0 files weren't very extensively tested. The Atarisoft version of Ms. Pac-Man, for example, is supposed to have two sectors with incorrect headers on track 30, as part of the copy protection, but those sectors are missing entirely in the TD0 file. If you try to play the game, it starts doing some really strange things that make it basically unplayable due to the protection kicking in. A conversion of the original to HxC MFM format works flawlessly, though (and I should really add that to the ibm5150 softlist).
I'm guessing most of the images are probably OK, but some others may still need redumping...

Already done  I also dumped a few other (non-booter) PC disks that I'll add later, and I'll have to get back to working on the PC-98 stuff at some point. So much to do, so little time...
