Re: The great MazezaM

While we wait for the improved graphics and levels of the upcoming MazezaM - here's the original in Super Spectrum vision :D The challenge to me was how long to convert 125 lines of ZX BASIC to the creatiVision. This is the original with 10 levels, although as it is data driven, it's as simple as co...

Re: Six new homebrew games for CV - wow!!!!!

Great find! - and yes there are 12 games in total!

To run in the emulator, use -g command line option, as the images are linear.

Re: Data register and pointers - where are they?

The creatiVision only has 1K of RAM - so 0 - 1023 addressable. Any address above this will just have the bit masked off. So maximum real RAM address is $3FF (1023). In bits this is 0000 0011 1111 1111 The address you are trying to peek is 1195 or $4AB In bits this is 0000 0100 1010 1011 So BIT 10d i...

Re: Cartridge ROM mapping

Here's an update!

Quick fix is to remove the LOADING PROGRAM and mark EOI for games like Bowling.

Unfortunately I am working away from home for next month or two - so can only investigate on weekends.

Cheers!

Re: Emulation questions

The emulator does just that - it emulates the cassette input.

This is why I wrote the txt converter.

Re: Salora Manager Disk ROM

I was doing some research on floppy disk copying, and was surprised at how cheap it is to do now. For Apple 2 GCR disks, well - the good old arduino is all you need - so less than 10GBP, 15GBP if you need the IDC connector. The software is open source https://github.com/adafruit/Adafruit_Floppy Ther...
