To add to your list, there are some versions (Europe or Australia releases) of unlicensed games that don't seem to be dumped at all. I tried looking for all of these, and I could find NONE of them. My source for some of these versions is from this page:
http://forums.no-intro.org/viewtopic.php?f=8&t=1008At the end is a(n incomplete) list of NES games confirmed to be released in Europe and/or Australia, and there are some games I have never been able to find in their Europe ROM form, so they probably are undumped. Also, in the first section, there's a list of (mostly licensed) versions of games (such as Prince of Persia (Spain)) that were undumped the time it was written in 2005. However, almost all of those games have long since been dumped (my GoodNES set has most of them), with at least one exception I know of (or at least it seems to be).
Here it is:
- Arctic Adventure: Penguin and Seal (Australia) (Unl)
- Fantastic Adventures of Dizzy, The (Europe) (En,Fr,De) (Unl) - On this page:
https://tcrf.net/The_Fantastic_Adventures_of_Dizzy, it states that there are some slight differences between this standalone cart version and the Aladdin version. It also states a palette change with a specific value of black that would be nearly impossible to notice on a real PAL NES, indicating that a ROM MIGHT exist of this version of the game, although it's possibly private.
- F15 City War (Europe) (Unl)? - F-15 City War is on the list of confirmed games, but I can only find an AVE USA release of the game (aside from the game being included in Maxi-15 Pack).
- Firehawk (Europe) (Unl) - Possibly same as USA version? A user named MrNorbert1994 ripped a PAL NSF of the game (although the pitch sounds 2 keys lower than it should), so there might be a ROM of that.
- Micro Machines (Europe) (Unl) - Possibly same as USA version?
- MiG 29 Soviet Fighter (Europe) (Unl) - Possibly same as USA version?
- Pyramid (Australia) (Unl) - I can find USA versions of the game, but not the Australian release (it's probably by HES, since the game was developed by Sachen)
- Super Adventure Quests (Europe) (Unl) - Confirmed to be the Europe version of Quattro Adventure (USA).
- Toobin' (Europe) (Unl) - Surprisingly, this is the only Tengen unlicensed game on the list. Possibly same as USA version?
- Ultimate Stuntman (Europe) (Unl) - Possibly same as USA version?
As I said before, I was unable to find any of these in ROM form, and I hope all of these will get dumped sooner or later. If any of you manage to find a ROM of any of these games, or dump the actual cartridge of these, please tell me.
