If there is fast ram in the machine, the game is currently using it! These things don't work in such a way that if I have fast ram, I use it for anything. On the one hand, the sounds and the images to be displayed must be stored in the chip RAM, in this case it makes no sense to copy these things in and out of the fast RAM. On the other hand, Amos also uses RAM for things that are not a matter of choice on my part, and believe it or not, this 512 chip limit can be reached very quickly, so the need for 1mb of chipram comes from this, and yes, it can be quite annoying if it is only a few kilobytes, but there is no way to cut it down! I would also like our ideas to fit in 512Kb chipram, but this is not possible without sacrifices. Despite all this, I dealt with the request and as an intermediate solution I shortened the game by a couple of sounds, so now it starts with 512c+512f config.I don't consider it an "update", but now it works. You are welcome.
