The games on this ROM appear to be built together, i.e. they cannot be completely separated from each other like most multicarts. Out of curiosity though, I messed with a debugger and found code to make the menu automatically load into each game:

Address line #1DEA0:
first two bytes to ff = hanuman quiz game
first four bytes to ff = malaria
first six bytes to ff = hanuman typing game

As such, I was able to get them into separate ROMs, but not in the conventional method as most multicart extracts. Additionally, I was able to trim Malaria into a smaller 40k file.

The ROM actually works fine; it's just overdumped by around 128K of extra data. I discovered the same YouTube video recently, alongside a video of someone who dumped an "alternate" version called "Bollywood 2007". Based on the 2007 version's code, I was able to reduce the 2003 version to run correctly.

I have attached both working ROMs below. Someone should probably alert the YouTuber that the file is actually a good dump, I wasn't really sure how to go about that...

I was attempting to edit the AtGames page on the BootlegGames Wiki, as I noticed the list of "pirated games" was a bit lacking. I recalled hearing that two old Sega games, Zaxxon and Space Fury, appeared on some AtGames consoles seemingly without license. Some consoles even have a bizarre "sequel" to the latter called Ms. Space Fury, which really just defies all explanation...

In researching, however, I came across something strange. In the game lists, both Zaxxon and Space Fury are apparently the ColecoVision versions; and are licensed solely through "Coleco", not Sega. I suppose it could make sense for - through some weird 80s contract - Coleco to own the rights solely for the ColecoVision ports. However, it goes much, much deeper...

As it turns out, there are lots of games "licensed" in this way. So much, in fact, that I can only count eight games licensed through Coleco that would logically be owned by them; the other thirty-seven would not be. Notable titles among this catalog include Konami's Antarctic Adventure, Taito's Jungle Hunt, Universal's Space Panic, Exidy's Pepper II, and dozens of others. Furthermore, a majority of these games have seemingly-fradulent trademark registries; either registered by Coleco directly, or a number of weird other companies that seem to connect back to Coleco. This has evidently been going on for about a decade; and with all this in mind, I'm shocked that I've never seen anyone bat an eye to it.

Does anyone know what the deal is here? I'm really lost as to what's truly going on...

Was there ever an update on this? I was quite curious to know what was on it.

If you still need a dumper, you could try contacting David Haywood (https://twitter.com/MameHaze), and determine where to send it from there.

This might sound like a stupid question, but does Thin Ice work if it's put in a different menu slot (e.g. as game #1 instead of #4)? I recall one of the menu slots for the 11-in-1 being finicky to work with for some reason; while the other ten slots worked fine with everything.

The new hacks are nice, I like the theming.

With the recent decoding of the NX-85's code scrambling, it occurred to me that the My Arcade "Pac-Man Pocket Player" handheld does a similar thing (though applying to the full data, not just graphics). That console is based on Sega Genesis/Mega Drive clone hardware, but features a newly-created Genesis port of Pac-Man; which as far as I know was never used anywhere else.

Out of curiosity, I analyzed the code of the Pocket Player, and found that the swapping method is quite simple. Using an extract of the Pac-Man ROM, I attempted to decode it using the EEPROM Pin Swapper tool used with the NX-85; but no matter what I input, I can't get it to unscramble correctly. I can get basically half of it to unscramble with the EEPROM tool; the rest I could logically do by hand, but I'd much rather do it by machine if that's a possibility.

Can anyone think of a way to decode this properly? The technical details are as follows. I have also attached the unaltered Pac-Man code if anyone wants to experiment with it.

Every line of code has its bytes flipped backwards, divided into sets of four sections. Pattern example:

00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F (standard)
03 02 01 00 07 06 05 04 0B 0A 09 08 0F 0E 0D 0C (pocket player)

By swapping pins A0 and A1 in the EEPROM Pin Swapper, the pattern is halfway fixed in a pattern like this:

03 01 02 00 07 05 06 04 0B 09 0A 08 0F 0D 0E 0C (a0-a1 pin swapper output)

Trying to swap pins A4 to A9, or any of the D pins, seems to screw the code up.

Interestingly there's a Nature Color Game copyright in that XB805 version... the CHR for it is blacked out, but filling it with letter tiles spells it out automatically. I'm inclined to say that this version still postdates the Nanjing release; as it has the updated tutorial screen text seen in Wonder Rabbit, while the Nanjing version doesn't (note the tutorial only displays in the multicart for some reason, not the extracted rom)

I'm unsure whether to consider Pikachu5 the "official" name or not; I write it that way mainly to avoid confusion with similar games. It would make sense as a title I feel, since the "5" presumably relates to there being five characters. I put a redirect on tcrf for "Pikachu (Nice Code)" toward the Pikachu5 article, so it is still categorized by both names.
