KingPepe's Palace of ROMs

Yeah, this is the same old Duck game you know. The difference? This was dumped from the original cart. The current (Unl) ROM floating around has no copyrights (either it originated from a repro or a HES multicart).

GoodNES 3.23b has a ROM named "Duck Maze (HES) [!]" which has the same copyright-bearing title screen, but a different CRC32. The different bytes are as follows (left: GoodNES 3.23b ROM, right image: your ROM image:
Code:
 
00005705: B1 F8
00005706: C1 B1
00005707: 71 C1
00005708: B3 71
00005709: C9 B3
0000570A: 0A 91
0000570B: 90 B3
0000570C: 02 29
0000570D: E9 10
0000570E: 0A F0
0000570F: 91 04
00005710: B3 38
00005711: 88 4C
00005712: 30 05
00005713: 06 D7
00005714: A9 18
00005715: 00 B1
00005716: 71 B3
00005717: B3 29
00005718: 91 0F
00005719: B3 91
0000571A: C8 B3
0000571B: EA 88
0000571C: 88 10
0000571D: 10 E8
0000571E: E5 D8

Hm, that section is definitely 6502 code, and the byte at 5705 (F8h) is the "SED" opcode, which enters "decimal mode". The NES' 2A03 CPU has no decimal mode. I remember reading on some web site (I do not remember the address, unfortunately) that Bit Corp. developed for Famiclones that still had the decimal mode, and had to fix their games to work on the original Nintendo console that lacked decimal mode. In other words:
  • Your ROM is basically Bit Corp's original version of the game and should only work on decimal-mode-having Famiclones, i.e. "Duck (rev0)".
  • GoodNES 3.23b's "Duck Maze (HES) [!]" is the updated version for original Nintendo consoles, i.e. "Duck (rev1)".
This of course means that your ROM should fail at some point in NES emulators that accurately lack decimal mode, possibly in a rather subtle way. The code seems to be called when starting a stage, and seems to have something to do with the score.

I remember the same web site specifically mentioning a decimal-mode-using version of Bit Corp.'s Othello, the existence of which now has become more likely.

I have uploaded a video that shows the Bit Corp. version of the game glitching in Nestopia, and as one forum reader confirmed, on an AV Famicom.

Gave that a try on emu, if you do avoid getting the hearts in the stage it seems the scores stays fine. But if I beat multiple stages in a row it may glitch since the scoring will reach the ten thousands (but I'm not good enough at this game to beat 3 stages in a row without game over).

EDIT: just beat 2 stages in a row with 5000 points as bonus. Skipped all hearts and it did softlock (reaching ten thousands)

New ROM dump:
http://www.mediafire.com/file/ommcdzdp09m0yxn/Rad_Racket_-_Deluxe_Tennis_II_%28MGC-011%29_%28Unl%29.nes
This is the TXC release of Rad Racket. This version operates under Mapper 136 which isn't supported in most emulators.

Thank-you, KingPepe.

Some emulators claim Mapper 136 support that however only works with one game: the Chinese version of Metal Fighter µ. Use this set of Mapper DLLs together with the latest "unstable" build of Nintendulator for full Mapper 136 support (source code), including the unhacked Chinese versions of Galactic Crusader and Mahjong Trap.

(Supposedly, Nestopia Plus! also has full support, although I have never been able to download that emulator because one apparently has to create an account with that bulletin board.)

Hmm... that's weird. Isn't this just a plain translation?
I know a dude on romhacking.net namely pacnsacdave who translates chinese pirates all the time.
It is also pretty weird, that the sounds engine is based on Now Production's driver.

Another ROM dump, TXC-published version of Venice Beach Volleyball!
http://www.mediafire.com/file/bdv5dkjyaoxk11i/Venice%20Beach%20Volley%20%28TXC%29.nes

Special thanks to NewRisingSun for this one! Like the TXC-published Rad Racket dump, this version operates under Mapper 136 which isn't supported in most emulators. You need to use NewRisingSun's Nintendulator build to properly emulate it.

Here's a few ROMs of Family Noraebang, most notably this pack contains the 3 other extension carts that were used for the machine:
