There are some hidden credits and copyright information in both versions of the ROM. They appear at address 0020 in the Famicom version and 015C in the FDS version.

Right after those credits, at 00E0, begins a pretty angry rant from one of the game's programmers, which was removed from the FDS version of the game. You can read the original, undivided version on the Notes page.
This hidden message can be found with any hex editor. Almost 5% of the entire ROM (2.05 kilobytes of the 41-kilobyte ROM image) is taken up by this otherwise inaccessible message. The message is recorded in romaji and reads like this:

You FOOLS say one thing, then something else later all the time. I worked ALL NIGHT working on what you told me to; don't say to me "it was better before"! Who the hell do you think is going to play this, with its boring bonus stage and the balls that get stuck? If you use SELECT to put the JOY right, that'll make it +1, you idiot! You're a sound company; quit ignoring pachinko sounds and trying to put these weird sounds in instead! Do you WANT it to be this hard to hear the balls?! I've left the PREVIOUS sounds, so edit this if you want to hear it. Set hex address AFFC to 1FAF and AFC4 to E0EE to get decent sounds. (Tiger_V & Kugi) Company "T", you idiots! GOU, you fool! Anyone can tell you what good sound is!

NANDE 6502 no decimal mode wo
nuitano ? decimal computer
nanoni ..... Mask no kiri
machigai ja nai?
Why did they take out the 6502's decimal mode [from the NES architecture]? It's a decimal computer... Did they mess up the mask cutting or something?
Interestingly, writing the bytes the programmer mentioned, after converting from NES memory mapping to the iNES file offsets (AFFC → 300C, AFC4 → 2FD4) lowers the pitch of one of the (quite frankly) annoying beeping sounds which constantly play during the game, indeed letting you actually hear the balls and game sounds. Why this annoying change was forced upon the game is anybody's guess, but it's a fairly clear case of executive meddling.
