Re: Newby question: Speech Expansion and the BBC Master

I think that there was a cartridge based speech expansion from someone, maybe sprow, btu it is not fully compatible (but maybe OS legal compatible?).

Re: Returning Beeb user looking for hardware assistance...

There are a few characters that look different in mode 7, including ~ which appears as a ÷. [ And ] appear as arrows. If you think that the disc controller is fine, a GOTEK is slightly more compatible and a bare drive costs about the same as the faster "MMC" devices. I would recommend the ...

You say that, but for a few weeks a few years ago, it was officially King's Landing. There are pictures. I think it was because it is on route from London to a local film location where lots of big films have been partially shot. OK, it was a week, 7 years ago. https://winteriscoming.net/files/2014/...

Re: Weeknight 'Virtual' Dev session #9, Thursday 14th January 2021, 7pm - 10pm (GMT)

I noticed that there are many versions of it, but not one with 5V level shifters built in ;)

PS I'm sure there are others, but it does seem like a good halfway house between a PiZero and a PICxxx.

And explain why when the beeb and the chip have 4 analogue inputs, only three are exposed ;) Voltage sensing or temperature maybe?

Gil and I did look at that and I was sure it could be done, but would have to be MODE 1, even with the reduced colours. Sprint uses 512x256 to make the cars look better and I think it would need even more for 3D. Does it really need to be 3D though? 320x256 3D with sideways RAM, 256x224 2D without? ...

Well, I think the beeb could do with more than one new shmup, and since you are going to write one anyway, you might as well start now ;) You know how much better it could be on the Master and that I will be targeting the beeb with one or two sideways RAM/ROM banks.

Re: Chuckie's ideas for game versions to the BBC

Technically should be easy, but as RobC says, you will need to compromise a little, colours Vs resolution. There isn't really much game but I would change fire to jump and up+fire for big jump. You might also want to trim the screen, depending on how much space the animation takes up. (Again, what R...
