Re: How to calculate memory location of a coordinate?

Can't you just do that?

Code: Select all

10 DIM LINE%(200)
20 FOR Y=0 TO 199:LINE%(Y)=#BB80+Y*40:NEXT Y
After, all you have to do yo get the address is to get LINE%(Y)+X

Re: How to calculate memory location of a coordinate?

The easiest and fastest is to use a precalculated table that contains 200 entries with the final address already calculated. In most of my code you will find these tables, just one example: http://miniserve.defence-force.org/svn/users/dbug/rasterization/linebench/display.s _HiresAddrLow .dsb 256 _Hi...

So, as far as I can see, what's missing from oric.org from me:

Re: Save a tape to a PC / Sauvergarder une K7 sur PC

Depuis quelques temps déjà j'essaie de transférer sur PC des programmes que j'ai écrits il y a longtemps, qui sont sur cassette pour les sauvegarder avant de ne plus pouvoir lire ces cassettes. (...) - J'ai essayé avec une interface Microdisc sur laquelle est branché un lecteur 3"1/2 : That's ...

Re: Oricium feedback and review thread

I don't know if its a bug or feature :) but the ship movement is getting bizarre. Even I don't press any movement keys, ship moves up or down time to time and this leads to collision with enemies and ship buildings everytime and I loose life. As I have only one life, I have to play the last level a...

Re: Cumulus Issues

Hello, I'm unhappy to say that my Cumulus had stop working. It was used only 2-3 times for about 4-5 minutes since buying it, but now when I tried to start and it is absolutely dead. Is there any support for these devices? I guess by "absolutely dead" you mean that the screen does not sho...

Re: oric sur moniteur RVB ?

Good question, I guess it depends of the type of supported inputs. The screen I have on my car for the rear view camera supports only composite signal, so that would not work on the Oric without some converter, but internally they probably all get converted to RGB, so I would not be surprised if som...

Re: List of games from 90's and 00's

Perhaps we should just check in Oric.org which of our software is there, and only write the information relative to the ones that are not in the database already?

Just run it in DosBox, this way you can run it in Windowed mode.

Re: Using Overlays with OSDK

I'm wondering about something... (Warning, thinking out loud) Let's say you use Chema's idea of using jump tables, there are actually two ways of doing that: #1 Have each module have just jump tables for the current module #2 Also have a global jump table for all the functions that exist across all ...

Re: Using Overlays with OSDK

I'm currently stuck in the middle of nowhere with a broken car, but I will think about it while waiting for the mechanics to fix the engine.

Basically something like Sedoric bank switching modules would work for you?

Re: Cumulus Issues

Only chance? I do not think so, because IC12 is D7 (bit 7), and D7 is a little bit special on Microdisc. This line can be driven, and maybe the Cumulus is 'more severe' than Microdisc (Cumulus schematic quickly examined but did not saw a specific problem). So, could it be a problem with timings in ...

Re: How to build a cable to plug a tape device ?

Look at the schematics on http://www.48katmos.freeuk.com/ports.htm

All you have to do is to connect the ground of the DIN to the ground of the Jack, and either the TAP OUT or TAP IN to the other pin of the jack depending if you want to make a recording or reading cable.
