much better with a screen, you can use it in config-less mode which just cycles through any HFE files on the drive; http://www.ukvac.com/forum/uploads/778/beebgotek.jpg I'm waiting for some smaller OLED screens that should fit in the Gotek fascia where the lcd counter goes; http://www.ebay.co.uk/itm...

Re: Galaforce for NULA (16 Colour)

There's ...

Re: Galaforce for NULA (16 Colour)

I'm interested in the image without the header, how did you separate them? I just deleted it with HXD hex editor - its at the front, I forget how many bytes exactly, I think Simon documented it in the readme, deleting it leaves the 20k of screen data. tools look good, any chance of a public release?

had a muck about with the joust (skirmish) palette, unfortunately the scores have a cross hatched background that means they get lost, and the pterodactyl looks rubbish, but the rest is looking quite close to the arcade.

Re: Loading a game from a cassette tape

another possible fault with old tape decks is the drive belt going. t's a black neoprene band. these get slack or harden with age and can start slipping. replacements are still available.

although i still own a tape deck i'd be loath to use it. some things are best left in the past. :wink:
