I'm just wondering about the reason for the decrement on zpTemp01? The return address stored on the stack when a BRK instruction is executed does not point to the address after the BRK, but one byte ahead (thus jumping over the byte following the BRK instruction). That is why I am decrementing it. ...

One more note today... I have found over 140 bytes free, following Dbug's advice. Maybe I'll need it for solving bugs that may appear... The trick is that I had many places where I needed to set up a pointer this way: lda #34 sta tmp0 lda #12 sta tmp0+1 The trick is (something related to this has al...

As promised... However the quality of the photos is terrible. I took them with my cellphone, and its camera is anything but decent. I wanted to use my photo camera, but it was out of battery. If I can get better photos, I will post them. In the meantime... http://www.defence-force.org/ftp/forum/chem...

A quick note today. Despite my lack of time I killed a couple of bugs and adjusted a couple of things these days. But what makes me post this today is not this small advance. I tried it on my Oric Atmos and, though it ran smoothly, my CRT TV picture through the antenna cable was horrible. So I built...

Thanks for your comments guys. Very nice progress .. just wondering what that flicker is in the demo video, you see it sometimes flashes the screen .. It flashes the border , just as the original version does in the speccy and c64. I thought it could be a nice touch. But if you dislike it, it would ...

Hi again. I did not have much time lately, so there has been little progress. Some bug hunting here and there... But in the meantime I think there are a few things you can see in the video in my previous post that are interesting. As you can see the engine is quite fast. There are 19 main characters...

Yep, the scrolling is quite faster in the speccy version. I guess the z80 beats the 6502 there... Also you can compare with the c64 version, which has a much bigger visible area: http://www.youtube.com/watch?v=wgwi9t-wf1o which does not have the nice continuous scrolling, either. In our favour I hav...

Okay, I have been working on this a bit more. I am trying to sort out a problem which appeared on the original Spectrum version with the rendering order of the sprites. Maybe you recall the teacher being drawn over the chairs but seated Eric being drawn over the teacher. Also something similar happe...

Hi Godzil. I have no experience with Mused or Sonix, but I recall they are quite advanced and compact in memory usage, though I am not sure they can export your music to be used inside your own programs. I used Wave 1.01 (which is a marvel) to produce the music in 1337. It is very simple to use, tho...

Not sure if this has already been addressed... I recall something, but I am not sure. I am experiencing problems when reading a dsk image modified by Oricutron inside Euphoric. I have been playing with WAVE writting a small tune for Skool Daze and I would like to use Euphoric's option to dump AY reg...

Ah thanks indeed JamesD. I think this player may suit my needs. I am not sure if I will be able to write any music as AY register values, but I will certainly try. And it should also be suitable for the basic sfx. In fact I was tempted to make direct calls to the ROM sound routines (music) so a song...

Thanks for your comments. And yes, I am using that source of information, which is invaluable. A lot of code is quite a direct translation from the z80 soruces to the 6502, though with some modifications wherever I think an alternative approach is better for the architecture of the latter. I am stil...
