Firstly, thanks to JoyG67 for writing the guide on fake pokemon games. I'd like to point out a fake pokemon game that I bought a while ago. I assumed the game was 'Digimon Ruby' not to be confused with 'Pokemon Ruby'. It played okay on my GBA but the writing was all screwed up and I couldn't make heads or tails of it.
Luckily by the time I realised it was a fake and stopped playing there was no negative side effects for my console, but others may not be so lucky. I should have known it was a fake by the fact it was not listed on the internet anywhere but I did not. I wanted to let you know that fakes are also found in the popular Digimon game series. Thankfully this was the only fake Digimon game I've come across but I wanted other buyers to beware.
