The cartridge itself came working and as described. I've had no problems so far and I have no regrets with the purchase. Great game which I'm happy to see get some English language support.
I was, however, disappointed by the quality of the plastic GBA/DS case that I paid extra for. I've bought GBC games from Retro Gamers that came with decent cases, but the one that came with Shin Megami Tensei was extremely cheap and won't even close properly. The box art itself was of okay quality, though I noticed a pretty glaring typo in the description on the back. As much as I want to have custom cases, I can't justify the extra cost if this is the quality that it comes with. I truly hope they consider finding a new case provider.
