Yeah, I promised the pc engine forums the rest of the batch we have here, and we're basically going to just start firing more off of the printer, and the funds will go into more supplies for the cards.
It basically just takes time. We can make as many as we want unless they suddenly stop making the eeprom that we use, which isn't likely, so, don't worry!
I am not a fan of the whole "oh, hahaha we're all out, sucks to be you!" setup, or the "oh here is "edition two. it means edition one is worth more!"" thing.
It's a homebrew game I made in my basement over the course of 3 years. It's basically meant to be played and enjoyed by as many people as possible instead of horded and flailed around about on the internet!
I am entertaining the idea of selling the ROM for like 15$, and then when you go to buy the card, I'll knock the 15$ off the card price, so people can at least play it on a flashcard or emulator while they wait.
I'm sure that will go well when it ends up on every ROM site ever, but, that's inevitable really.
