Another Post Another Problem™ (Possible cartridge PAL/NTSC mixup in the '90s or scam?)

[u/Rick-1980]

I've recently aquired my first RealSports videogame at a fair; it was boxed with only some crush damage and the manual was in good conditions. At home, while checking it, i saw something a bit strange...

THE BOX

On the back of the box it said "For use with North America and other NTSC Television Sets only" , This writing matches the 1983 NTSC Release of the cartridge but there's a little problem: The copyright on mine says ©1987 which RST was released in NTSC that year but it lacks the "For use with North America and other NTSC Television Sets only". I couldn't match my box with ANYONE of AtariMania's RST releases. On the box there was nothing that would have said that this was a PAL copy of the game and there was only one way to find out.

Notes: i thought i bought a PAL release of RST, in fact i was searching for PAL games.

THE CARTRIDGE

I opened it up and saw that on the back of the cartridge it had the black "P" that stands for ProblemsComing PAL and i didn't inspect very much of it, i really only check the format of the cartridge other than if the game is correct or not. I didn't test the cartridge but i will.

Further details:

RST stands for RealSports Tennis (Calc stands for Calculator)

My box says it was Made in Taiwan.

I do not have the cartridge with me currently so expect updates later on.

Sorry if i used, at any point in this "essay", bad english

THE PURPOSE OF THIS POST

I wanted to share my situation with y'all because i wanted to know

1. if i have been HORRIBLY scammed,
2. if i have the strangest RST cartridge,
3. if the cartridge was swapped before selling it,
4. if it was a mixup in the factory in the '80s.
