yeah yeah, well finally managed to get into project. The problem with me nowadays is not so much motivation whilst doing a project or even getting sidetracked but motivation starting such a big project especially now its on disk. Managed to get dskbuilder to rebuild disk properly, convert to mfm and...
It was good to show some progress for O-TYPE at CEO visu in Paris a couple of weekends ago. Unfortunately since then, due to illness i'd not done much over last week. However i seem much better now and have constructed the framework of the game on disk (using dskbuilder). Now setting up the scripts ...
Ok a few developments but not anything like as many as i'd hoped. For some reason while my heart is in it my mind hasn't been so much. Got the Motorcycle scorepanel finished (or near to it). The game is spread over 5 levels and each level contains a number of scenes. For the first level i have 4 sce...

So that bits pretty much done. On to other stuff. The sprite management engine is a complex beast. It currently handled all sprites including ground based sprites (such as Tanks, vehicles and gun turrets) and air based sprites (such as planes, player crafts, projectiles). To always ensure air based ...

Hey Dbug, what date do you leave and what date return? For me, i'm supposed to be working on this big project called O-Type. Doing some design work around the cut scenes/storybook type of parts. Its all essential, but saying that so is getting some score written down. Anyway i'll soon update Otype f...

I was recently reading up about the Sam Coupe and noticed they used a motorola MC1377P chip to convert between RGB and composite. The data sheet is here... http://www.datasheetcatalog.org/datasheet/motorola/MC1377DW.pdf The only problem is it requires a minimum of 10volts to drive it. Internally one...

Yes ibisum, thats what i want. It could also be useful to set the NMI reset flag though thats less useful i guess. The keyboard thing could have been really useful when trying to fathom why things behaved the way they did in Impossible Mission when entering the screen and immediately pressing down. ...

Could this same .bss be used for compiling zero page routines? For example zero page routines only ever reside in zero-page once the program is loaded and the driver has shifted the code to zero-page. This means I have a difficulty when i try to do self modifying zero-page code.. ZeroPageRoutine sou...
Ok after a change of heart i've decided to map the road just like the original demo. It means the game runs the same speed as the original demo (very good), is much simpler to code but will use a little more memory for road graphics. Anyway currently i have created all the road verges, and some back...

There are curcuits available to connect the RGB output of the Oric to a scart connector but they require both an external psu and some hardware skills. French Oric's came with an extra pin on the RGB output to provide power i believe. For Channel 36, thats what i use here. Under the oric are two sma...
Have just started laying down some code. The first part of the game will be similar to spyhunter. Still vertical but you'll be in control of a truck attempting to get to the airfield in time. Anyway more on the storybook later. I want the road to be independant of other background objects so that it...
