- Bad Export for You: The special decals in KAIDO: Touge no Densetsu is completely removed from the Kaido Racer 2 and Tokyo Xtreme Racer Drift 2, both international releases.
- Downplayed in Kaido Battle; some cars were swapped out before its North American release due to Executive Meddling. Alfa Romeo replacing Lotus, for example.
- No Export for You:
- Before Tokyo Xtreme Racer, Japan has it, Europe has some of them, but if you live in North America? Too bad! (With the notable exception of Tokyo Highway Battle).
- Kaido Battle (TXR Drift) was released in North America, but not Europe. Kaido Battle 2 (Kaido Racer) was released in Europe but not North America.
- Racing Battle: C1 Grand Prix is Japan-only.
- Sequel First: Drift is actually a prequel to TXR3 in terms of Japanese timeline, but the Westerners have received the latter first. The former was not made available till 2006, pretty much around three years. This led to a downplayed example of Bad Export for You (see above).
- Unwinnable by Mistake: In TXR3 there is a racer named Whirlwind Fanfare that is impossible to race against as the money you need to race her is only 10 credits above the money cap in the game. This was due to an error in the currency conversion and why all games afterwards have used a currency similar to yen instead of dollars.
- What Could Have Been: There was a nitrous system which was planned to include in Shutokou Battle 01. However, it was Dummied Out, and you have to glitch them in order to use it. It was finally available in Shutokou Battle X.
- Deep into the files of 01, there are some cars that have been Dummied Out and can only be found via glitches or codes. This includes a Porsche-lookalike which was supposed to be a planned car for ZERO (before it was changed), and a Peugeot 406 which has bodykits inspired by Taxi 2. See here.
- Also, variations of Toyota Hiace were planned as Secret Cars.
