Thanks to Tokra for blazing the trail and getting VGA working I have modified my game to work in native VGA.
Anybody that has a 80col to RGB adapter should be able to connect a VGA monitor and play
As far as I know this is a world first and I would consider groundbreaking for the 128. Not hard sadly as nobody else seems to be doing anything interesting. It's native 128 mode, not 64 (not many games on the 128 anyway). It uses the VDC not the VIC (hardly any software at all, let alone games) and finally it pushes the VDC into VGA mode (As far as I know, Tokra and the VGA mode mania demo is the only other native VGA software on the 128 at all).
I have some polishing to do, tidy up the graphics and put in more levels, but the first 7 are playable.
I would greatly appreciate anybody who is able to test this letting me know. I can give you a link to the latest version.
Yes, that is a photo of it running on my BenQ monitor. Yes, I am using my adapter which plugs directly into the 128 and has a VGA connector on the back. It makes it extremely easy to plug a BenQ into it. Any adapter solution should work though, right down to the simplest resistor circuit with no brown fix. As long as you can connect it to the right pins on the VGA plug it will work.
Having the multisync monitor helps a lot as I can boot directly in 80col with normal 15khz frequency and still see the picture. I can also directly compare the PAL version against the VGA version on the same monitor

Again, It's not much use in VICE which doesn't emulate the VDC well at all. This is a real hardware only game.
Actually, the VICE mode by holding fire doesn't work at the moment. The changes for VGA really broke it quite badly. It's a completely different character set for graphics too so I can't even make it switch back into 15khz mode easily.
trantor, yes, in theory I am selling them. Waiting for PCBs though. I am actually trying to sort out a US retailer who will help with manufacture as well! So fingers crossed they should get a lot easier to purchase and also be available locally in the states soon(ish).
