oh sorry I thought it looked like mode 2, my bad
I disassembled zalaga years ago and remember it used illegal opcodes to do pixel flipping with the minimal number of instructions
not a fan of such things myself but it might be worth looking at ?

Re: BBC Bomberman
Yeah, illegal opcodes is something I'd steer clear of as I'd like it to work in as many emulators and hardware variants as possible.
At present I'm ok with the speed of render, my current stumbling blocks (except finding time of course) are available memory and the need to convert to using sprite display lists within VSYNC compared to in the mainline code.

I played around making a different version of the loading screen.

box art suggests he's carrying a green thing. I like the belt blue though.

Thanks for contributing this loader screen, it looks great.TobyLobster wrote: ↑Sat Jun 25, 2022 1:14 pm I played around making a different version of the loading screen.
I've just got around to adding this to the game, and also modifying it to use sideways RAM for most of the data, I have room to breathe again!
Thanks
Re: BBC Bomberman
I've been bugged by the music in my port running at 50Hz (from VSYNC) rather than the native 60Hz as intended.
Although it sounded fine in isolation, when switching between NES and BBC it's noticeably slower.
So I've finally managed to update the source to play the music at 60Hz on the BBC. Making use of TIMER2 on the user VIA.
Other changes since the last release are :

Other changes since the last release are :
- Added demo key data - this is for a replay of the keys to simulate being pressed when the demo is running.
- Appended machine code to loader BASIC - this is the SWR loader to make it quicker and more concise.
- Loader screen dynamic rebuild - rebuilt if source PNG changed.
- Loader screen now EXOmised - saves space and loads much faster.
- Improved compatibility with BBC Master - in relation to SWR bank switching.
