BeebEm and viewing the callstack

I often find myself wanting to know the call trace to a particular breakpoint. Would it be useful for BeebEm Debugger to display the callstack when you are stepping through the code?

out of some idle curiosity it would be interesting to understand the dissasemblies for the likes of EXMON II and Wordwise. I imagine Exmon must be reasonably straightforward.

Theres about 20 pages of info about DFS 0.90 in "Within the BBC Microcomputer" By Roger Cullis.

It contains a description, a Gazetter, a list of ram usage followed by the JMP/JSR routes. It is a useful starting poiny but it is not a dissasembly.

yes, in the original game the data is in its own file. I just read out each byte of this file into an array "tgd" (the game data) in the javascript, os it was just a case of porting the engine.

cheers. The only difference is that my version has everything in one file and it then relocates down in memory after loading, so they are identical apart from that.

I think I have a different version of Wizzy's mansion.

I tried to do a hexdiff with some tool I downloaded but it couldn't cope. My version also has a rude message in it.

Any ideas of a good hex/binary comparison tool. I also tried M$ Windiff but I don't think that can compare binary.

Old adventure game in Javascript

I've ported the old 1982 adventure Katakombs to Javascript now, as a little task to pass the time. It was pretty straightforward as it has a small game engine. Although the Javascript looks a lot larger than the original BASIC. The data file is unchanged from the original BBC version. The Javascript...

There are 1024 bytes of screen data. Each screen block is half a byte so there are 15 different types of tile but I don't think all 15 are used. So one byte holds two screen blocks which are 8x8 pixels and a screenful is 7*10 blocks = 35 bytes. Excellent Well Done. There was always some think magica...

Can you still use hardware scrolling if you shrink the screen in this way? I was thinking a little more about this, and realised that it really makes a huge speed difference to shrink the Mode 2 screen to 512 bytes wide (16 characters instead of 20). This way, you can dispense with the lookup tables...

I was thumbing through the WW+ reference manual and it looks like it has its own variant of BBC BASIC. Is this correct or did it hijack the real BBC BASIC?

You could try using SDL . It's a cross-platform API that wraps DirectX on Windows (so it's fast), but also works on the Mac and UNIX/Linux. So, if you restrict yourself to the standard C library and the SDL library (just one single DLL for Windows) then there is no reason why you cannot code it in ...

yes thats exactly it but I don't have any experience with DirectX etc so don't know the best approach. Ah, I see! So what you are really trying to do is create a sort of mini-emulator or wrapper for the graphics functions. I'm afraid that is a bit outwith my area of expertise. Kind regards, Francis.
