I think there is a problem with sprintf.

int le=1;
char strng[40];

sprintf(strng, "%d", le);
printf("LE=%d LE=%s\n", le, strng);

I get
LE=1 LE=15

Depends of the performance you are looking for, but the PLOT and SCRN functions can be implemented like that in C: void PLOT(unsigned char x,unsigned char y,unsigned char car) { unsigned char* screen=(unsigned char*)0xBB80; screen[x+(int)y*40]=car; } unsigned char SCRN(unsigned char x,unsigned char...

I used the following function. This function returns pseudo-random numbers that are power of 2. The argument n is used to define the upper limit of the returned values, the higher the n the lower the upper limit (e.g. for n=6 the function returns values 0, 1, 2 and 3). int rseed=3; int rnd(char n) {...

I don't need anything advanced. If rand() returns numbers between 0 and 1 is all I need.

Any ideas how to implement Basic's RND (random numbers between
0 and 1with uniform distribution)?

Thanks

Thanks Dbug. I will use this for the moment, see how things go
and decide if I need something funkier.

I am planning to do something in C for Oric and I need the Basic's functions PLOT and SCRN. In the OSDK the hello_world_advanced is included in the C samples. In this project there is a function written in assembly which is called AdvancedPrint and is equivalent to PLOT (I think so). Is the Basic's ...

I retested Oricutron on kernel 3.0.0-26 and looks improved. Oric can now be simulated at 66% of its original speed. I did some experiments. In the picture OricutronUp.png Oricutron is up and running. Three processes (oricutron, pulseaudio and X) consume 100% of the CPU. In the picture OricutronDown....

Are you talking about an annoying high frequency sound? I am experiencing it too.
Xubuntu 11.10, oricutron 0.9.

Spectrum version is really good. Sharks look very realistic. Oric version is just decent. The C64 version is a pure joke:

Impressive! A complete scrolling game with just a few Basic lines.
