New version of Minus4j released.
Well, I've decided to release what I've done so far so that Plus4world (and anyone else) can get the new bits.so head over to my MINUS4 site and get the latest one if you need it. Heres a list of the changes...
Updated rendering engine ported from Minus4w, should handle more cases.
Updated CPU processing ported from Minus4w. More games should run.
Fix a crash in the CPU processing.
Changed the colours to what Yape uses (much nicer)
Added FLASH attribute, so things now...flash. (Manic Miner keys, Monty pick-ups etc.)
Fixed the rendering frameskip - it was always skipping at least 1 frame *idiot*
Fixed the overflow flag (V) on the ADC instruction. Mercenary now works!
Added the new "joy" paramater
Fixed commando - added several undocumented NOP codes.
SOME vertical scrolling games work.
More Progress.
This is pretty neat as it means I can show new things as code rather than video. However the new version of Java appears to be a little sluggish for some reason, and frame rate has dropped a lot. In the past I used to get upto 450FPS but that has now dropped to around 70fps - without scaling...pooh. I hate Java...
Still, when all said and done - how cool is it to have xeo3 actually PLAYING in a web page!!
Life in the old dog yet....
I've managed to debug Minus4j using Eclipse. This is a JAVA based IDE and its pretty spiffy in places. Couse...being Java based, its a bit sluggish - even on my new monster PC. Oh well, at least I can single step my applet!
So, which one hurdle down, another begins... I've ported a lot of Minus4 back to Minus4j (its pretty cool that the code bases are virtually identical, coz I can cut and paste most changes), and the bug I had was simple that the mainloop on Minus4w had changed a bit, so a quick change on the java side, and we're all go!
Minus4j now has inverted characters, the flash attribute, and a proper hardware cursor (not that anyone really used it outside of basic of course... but still... I'm also trying to update the CPU module as well, as minus4j is prone to crashing, and doesn't run some games (like Mercenary). I'm having a little trouble getting Mercenary to work - oh it runs and all, but it doesn't get past the intro. I'm sure this was a BCD problem, but I've ported the BCD stuff back from Minus4w and its still fubar. Mmmm...
What would be nice is if Plus4world could just allow EVERY game to be played online. Sure some wouldn't work, but I think most would and it would be easier to exclude some, then include them all.
Anyway, back to work I guess. I need to try and fix this BCD issue (if I can find it), and then add an option for joyport swapping to the paramaters (another request). I would love to add sound, but I'll need to look into doing dynamic WAV's under java. I know the C64 emulator can do it, so I might disassemble that and have a peek.

Intermission....
Albatross!! Albatross!!! Get yar Albatross here!
okay... Got slightly side tracked as a beta of Call of Duty 5 came out today so I had to have a blast at it... FAB game, got to be one of my fav all time games the COD series. Anyway... Aside from that I'm trying to update Minus4j for Plus4world so they can get more games on line, and so its well....better.
It does have some issues and I thought I'd port back some Minus4w stuff. This should be easy as the source for Minus4w originally came from Minus4j. So it was all going swimingly well, then BANG! It all fell apart. I have the drawing code ported back and as far as I can tell its now identical, except Minus4w works, and Minus4j jumps up and down like a rabbit on a pogo stick. So now I find myself in need of an applet debugger. Im sure it'll be obvious once I debug it, but until I do... I'm a bit stuck. Fek. I could undo it all and then just fix one issue at a time, but that seems silly as Minus4w is much bette over all.
*sigh*

Almost there....
I've just about got my PC setup again, althought theres always going to be apps I've forgotten about and will only rediscover later on. I thought I could get away with just installing the C# Express edition for all my needs, but alas no. I really need macro support and it doesn't have source control built in so I'll have to install the full Visual Studio again. I do hope to do some C# Express projects for the debugger to allow people to write plug-ins without having to buy the full visual studio though.
Speaking of source control... I've reinstalled Visual Source Safe so I can get access to my old repository but I'm thinking I want to install SubVersion. This would bring me upto date a little and allow others to check stuff in/out of my depo. Russell's been moaning at me for months to let him get access to the debugger and so he can keep upto date with the XeO3 source. I have come across a tool which converts VSS databases into subversion ones, so I'll have to give that a go - I like having all the history for them, but as long as I still have to old VSS repository I guess its not a huge issue.
The guys wanting to do a CPC+ version of XeO3 got in touch (again - I missed them 1st time around; my bad), so we'll have to have a chat and see if they meet the criteria for offical developers (Yes, I'm a picky bastard...).
I'm having a slight issue with my new install as it's a 64bit OS, my 32bit apps are struggling to talk to the parallel port. Still, once I get DevStudio installed, I'll see if I can fix all that. It should also mean I can release 32+64 bit versions, or I might take the opportunity to port them to C# and mono.
I've also downloaded a VMPlayer and will get a mono vm image so I can start doing Linux support. This will let me play with Linux without having to dedicate a machine to it, or even reboot into it. (I hope - depends on how the free vm player works.)
So with any luck... back to normal next week!

Malcom Scot Maxwell - Game coder and project leader
Dave Jones - Boss, Big cheese, and all round pest.
Andrew Innes - Front end, stats and general coding.
Martain Good - CG artist (did all the unicycles!)
Steve Hammond - Manual
Mike Dailly (Me!) - Level Editor, Uniracer compression, SNES framework and tools.
Colin Anderson - Music and effects.
Craig Arbuthnott - Head of testing
And I cant remember the last two. Testers I think....?
Head over to the staff pics on the Flickr account for better (all be it older!) pictures of some of us.

Demo coders....
There was a post on plus4 world about how to teach new people to code on the Plus4 and it got be thinking about some pet hates. Demo coders are renown for keeping sources to demos secret, never releasing anything but binarys in case someone steals their ideas. Others don't release code becasue, well... demos are usually hacks that are horrible bits of code and they don't want anyone to see just how much of a hack it is. Great Demos usually flow like works of art, but if you saw the internals, then its like being told how a magic trick was done, and the wonder falls away.
Still, I was thinking.... I never really code demos because, well... I'm not very good at them. Sure I can code things so they run quickly, and I can code things so that they're small. But I've never been good at prducing great demos folk really want to see. That said, I think theres a market (as it were) for demos that simply show how to do something. Kind of like online tutorials, simple demos that show off a simple effect and how to pull it off. This would allow others to use it and do what I can't, make great demos - or perhaps even use the effect in a game!
I was watching the demo posted here and was trying to think how they did the full screen scaling coz I think it would be cool in game. I think now I know but I also suspect that if the source was available I'd be much more interested in using/trying that I am now. Anyway, Csabo over at plus4 world is thinking about this too and I think its a great idea. If nothing else, it adds something valuable to the scene - which is what its all about now.

It's alive!!!!
I've rebuilt my PC, got a hold of a version of Vista64 and got it all up and running. I've also installed my new copy of office so my email is working fully again, which brings me to another point. If anyones been trying to get in touch and I haven't responded then feel free to ping me again as email should be back to normal.
I now have to reinstall all my normal software again, which will take a couple of evenings I guess, but I hope that by the weekend, I'll be back to normal - but with my fancy new quad core. I have also gotten two new terrabyte drives to try and get rid of all the little drives my PC was using, so with any luck... I shouldn't have to do this again for a long time!

New bits!
My new bits have arrived at last! So I can finally get started on rebuilding my shattered life...err..PC. The motherboard looks pretty good and actually has 4 DIMM slots, not the 2 I thought it had (the picture was pretty small), this means I could go up to 8Gigs of RAM if I want to (thanks to Vista64).
However...first things first. Build and reinstall is the job for tonight, if I get a chance - hope so. I'm gonna go and buy another 1Tb drive though so i can cut down on all the smaller drives I keep having to put it. My old primary was 160Gb, then I had a 240Gb and a 500Gb. So sod that, time to clean up and just get 2 1Tb drives. They're getting pretty cheap now, ebuyer actually had an external 1Tb for only £85(ish). This'll make life much easier and I'm beginning to get retro withdrawal!

Picture Fun...
I've been having fun with my new camera, and have been out specifically to take some nice piccys (something I plan to do more of if i get the chance!). I want to play more with the technique known as tilt-shifting. This is where you make real things look like models, and its very cool indeed given the right image. So I went up the law hill (the large hill bang smack in the middle of Dundee) and took a few images, then had a go applying the tilt shift effect to them. The image shown here is one of them, but I'm uploading more to my flickr account along with any other pictures I take (since they can stay full res there).So if you want to see some of my piccys, check our my flickr account now and then.
