rtype bbc micro conversion

[Chuckie]

Looking at what has been possible with recent conversion I was thinking about Rtype. It was converted to other 8bit platforms but never made it to bbc it seems

Personally I’d look at the Nula thread.

Think the colours avail would really get rtyoe looking awesome on beeb maybe master.

I think you are looking Master + NuLA as you would need a double buffered screen to allow maximum time to draw without tearing or flicker and NuLA for hardware pixel scrolling 1 pixel every two frames without the hassle and possibly in 240x256 psudo 16 colour mode.

I did do a proof of concept for the Model B, which shows the scrolling and landscape timing (coloured lines) taking at most 1/4 of a frame and usually 1/8 of a frame.

Watch in 720p50 for an idea of how smooth it could be. https://youtu.be/qZutBb3bCqw?t=24

Gil an I did this BITD which was partly influenced by R-Type.

Doing it* is possible, me doing it is unlikely although I would love to, I don't have the energy to stick with a big project any more. If anyone wants to do it, I happy to share my code and ideas but it will be a huge job.

*It being something that looks similar and feels like R-Type, but there are some parts that just aren't practical.

I would be interested in looking at the code thanks

The drawing and scrolling code is at the end of this thread, along with an explanation of how it works.
