|  Re: Cartridge ROM Hello World
I'm wondering what the OpenC16Cart is. I'll Google it now.  BTW, A couple years ago, I was working on some Plus4 cartridge memory configurations for cc65. I did well, but right now, there are two problems: 1. the RAM behind the cartridge is not visible. I can port Hidden64 there, and that should help. 2. the 32k version that keeps the cartridge active except when accessing the kernal (plus4cart3) is not working: the test program usually locks up while displaying the text. I think I'm not handling interrupts properly. I believe I have the Plus4 PRG and some Mapping documents and should pursuing them. I have version 1 for 16k cartridges and version 2 for 32k setups that treat the upper 16k as data in a way similar to Hidden64: it's banked out by default and banked in upon access. They are at https://sourceforge.net/projects/cc65extra/files/memory%20cfgs/.
