Re: ULA Paint

This directory seems no longer to exist.

I suggest to create a UlaPaint directory in :

Re: Lode Runner for Oric by [raxiss]

Waou !! What impress me the more is: 3 channels music + sound fx !! :shock: and all that with independent volume control. Has this already be seen on Oric ? It's very very great !! The possibility to resize the sprite. Because dynamic selection of sprite dimension makes it difficult to optimise with...

Re: Castoric : Raycasting on Oric computers

A possibility could be to use a single column back-buffer, render the background in it, then render the walls, then render the sections of sprites, and finally copy all that to the screen, that would be enough to avoid all the flickering problems. That's definitely a good idea. My recent works on c...

Re: Master Paint and Joystick

Some info : The original joystick routine is at $6FA0. In the ZIP file you can find also the source code (drv.s) which uses my ijk-driver which is already available from github . The driver patches and hooks the joystick handling. The return status need to be placed at $80. I really wonder how you ...

Re: Missing games from Oric.Org

I forgot to say that control keys are:
- UP/DOWN LEFT RIGHT for moving
- X and C for shifting
- SPACE to open (you need the key)
- ESC to leave

Re: IJK interface diagrams.

Waou !! :shock: :shock: :shock:

This really makes think of a Battle Zone For Oric because the arcade version had two joysticks !!

Does anyone know if this could be used in this type of game source ?

Mr Vocid

A little french game (vertical line) that has never been published in the past.

Here's the translation of the game intro (for non french speaker):

Will you manage to get M.Vocid out of the Huwan laboratory ?
Tips: M.Vocid turns left when he encounters an obstacle.

There it is! In French sorry, but I guess automatic translators can do the job if any non-French is curious.

Waou :shock: nice work

It's very difficult to extract the meaning of an assembly code without knowing the design.
Well done.

Thank you very much for this in-depth reading. Each time you peer-review my code, I'm impressed by the relevancy and the accuracy of your remarks. It's a very valuable reading that you do. Not only because it will help to improve the performance but also because it requires high skills to catch how ...

Re: Wolfenstein / DOOM for Oric : has this been done?

Not sure to understand well because it seems to me that it is already done the way you're suggesting (except the fixed 8.8 that was not required because all steps are precomputed in 8 bits). I think you had already suggested me to used precomputed dda steps rather than computing them live. Can you l...

Re: Wolfenstein / DOOM for Oric : has this been done?

In case it could serve as inspiration; Waou !! this game looks great. Thank you for the link. I find they really did a good work with this ray casting engine. They reach 25-30 fps !! amazing !! It makes me think that Oric would also deserve to have such a game in its asset. Because we have the same...

Re: up loading files

Hello yes .. I think this is a limitation of the forum.

Either:
- pack your files into a single compressed archive,
- or upload them on an other location and just publish links to them,
- or create several post on your thread, each containing up to 3 files.

Re: Oric emulator in Python

Sounds very interesting. Moreover, you had already worked on an emulation of the graphic chip. so it could be a good start. What I am especially interested in is the possibility of automating some non regression test. Recreating an Oricutrom looks ambitious. But we can have some exclusive features w...
