Re: Electron Exile DFS image - fixed

While finding useful disc images to go onto my Gotek, I found the "Exile-fixed" image and couldn't remember what is was. Then I found this thread, and noticed that it's not clear whether password-free version of Exile can load savefiles correctly. Well, I've just checked, and it can't. So I've merge...

Re: Master Ram Board or Second Processors.

It's a good question, and one which Electron owners faced back in the 80s. The MRB was the winner back then because it was cheaper, easier to understand for the casual user, fitted inside the case, and offered a Turbo mode which gave some speed benefit without breaking compatibility too much. These ...

Cumana just put proprietary drives into cases. You need to figure out who actually made the drive, and then try Googling that.

Re: Video Timing

The Sony TV also has another problem with BBC machines, which is unrelated to Frogger. It sometimes can't do the sub-pixel antialiasing in Mode 7, displaying a sort of checkerboard effect instead. This tends to go away if you blank the screen (eg by changing mode).

Re: Video Timing

Good news - I've managed to solve this problem! :D And I think it does shine some light on the video timing issue actually. All I did was switch to a different TV (a Samsung Syncmaster 510MP). On this other TV everything works fine. So this means that the first TV (a Sony) wasn't entirely happy with...

Re: Cartridge slots

Do they sit on the 2Mhz(?) data bus? Yes they do. I'm not very familiar with the 1MHz bus, so I'm sure others can do a better job of explaining, but the cartridge slots provide access to the processor's address and data buses, plus Phi0, IRQ and NMI lines etc. I think this makes the cartridge inter...

Re: Video Timing

Good point, that makes sense! My Master does boot up into a shadow ram mode. Explains why it worked OK in Master mode on BeebEm. EDIT: I have reconfigured it to boot to a non-shadow mode, but the problem persists. Definitely works OK in BeebEm (in Master mode). I checked the value of HIMEM to be cer...

AP6 rom incompatibility with Codename Droid

I have just discovered a rather odd incompatibility betwen Codename Droid and the AP6 rom. With the rom inserted, the game runs, but black background tiles are filled up with mostly-white but also slightly randomised corruption. I'm talking about the ADFS disc version. I'm not suggesting that this i...

Re: My final unanswered Exile question

I struggle to imagine how it could be much better than it already is. However I do have a practical suggestion, which is whether it could be ported to the 6502 second processor. This would free up a lot of memory which could be used for more sound samples perhaps?

Re: My final unanswered Exile question

it has just occurred to me that the algorithm matches the plot of the novella: in the story, Triax adapts the natural cave system to his own evil plans, whereas the map generation system allows local manipulation of a "naturally" generated map.

It's genius.

Yes, higher numbered slots have priority (ie, the OS checks them first)....

It needs 5V from somewhere. Where is entirely up to you - you might be able to get it from the AP3 itself somewhere? I've had a quick look at my Pegasus board, and whilst it might be possible to pick up 5V from one of the headers where options are set, it would be a bit messy. What's more, if I mov...
