V1.1 not working, it does nothing, the same as 1.0
OK, thanks for testing! If the screen just remains black, I guess that means that no cartridge code is being run at all. (The first thing the cart code in v1.1 does, after making sure the VIC-II chip is enabled, it to set the border color to blue, and then it changes the color several times during the initial startup sequence.)
At least it's useful for me to know that although a cart image works as it should in the VICE emulator (with "MAX Machine" as the selected Model in Settings), that doesn't mean that it will work on an actual MAX Machine. (I'm assuming that everything about the physical cartridge itself, and the pinouts, are appropriate for the MAX in this instance.)
A new version v1.2 is now available, where I've made some further adjustments (e.g. removed a PAL/NTSC check, which means there will be a little sprite glitch near the left border on PAL C64s. But the MAX is NTSC only anyway.)
But I fully understand if you don't want to spend any more time on testing this game on MAX, though.
V1.2 not working in MAX.
I have tested all 3 versions in C64 and all 3 are working, as you know all MAX cartridges run on a C64, but not the other way around.
The cartridge's hardware must be fine because I can run other 8K MAX games on it. I followed the same process that with OLD MINE, first converting the CRT file to BIN (The file needed to burn a EPROM). For this used WinVICE's cartconv.exe
cartconv -i WaveHero.crt -o WaveHero.bin
And then burning the EPROM with the BIN file.
The hardware is configured in 8K ultimax: #EXROM=1, #GAME=0 : start $E000-$FFFF #ROMH
I will have a look to the crt format when I have more time.
Thank you for testing again, and for providing all the details of the process you use. I see nothing wrong there.
I've verified that the output file from the cartconv command you mention is binary identical to the ROM file I used when creating the .crt file, so the crt header/format seems to be correct.
