Just noticed that I am doing: ;g_rand_seed.r2 = X; txa sta _rnd_seed+2 ;A = (g_rand_seed.r1 + g_rand_seed.r3 + (A>0xff)); ;*carry = (A>0xff); ;A&=0xff; lda _rnd_seed+1 I supposed I modified something, as this could be optimized to ;g_rand_seed.r2 = X; stx _rnd_seed+2 ;A = (g_rand_seed.r1 + g_ran...

Greetings again.

I am back from my Easter holidays, and ready to resume work on 1337 (as soon as I have some free time). I already killed a couple of bugs yesterday :)

BTW, I had no feedback from the alpha testers yet. I don't know if this is bad or good news... I fear it is the former?

Maybe not the best random routine around, but this is the one from Elite, and I am using it in 1337... It uses a 6 byte seed for galaxy creation and a 4 byte rnd_seed for random number generation. The init_seed copies the base seed for galaxy (which can be ommited if you only want the generator) and...

Really nice!

It is clear that the release of oricutron sources and its cross-platform nature is giving out very nice results!

Somebody please pick up my heart, which has rolled over the floor :)

Glad that some posts made me clear it was an April fool's post... I didn't realize at first.

So, at least you scared one person... me :)

Yeah most probably, JamesD. Also the fact that Fabrice Broche reads the Telestrat keyboard with 8 cycles is a good clue about what we can expect from the hardware. Twilighte, I really think that what is needed is come up with several small test programs (like the one I did) that could be loaded into...

Greetings again. Very very little time lately for oric things :( I have not done any advance in the game itself for that reason, but have been thinking about the plot and the missions and tested a few things. It could even be possible to have alternate "paths" within the solving tree, depe...

I really hope you can get one, as they are quite rare. I am sorry I don't have one (not even a working atmos right now), as I would at least lend it to you so you can make your tests.

We really need a replacement using modern data storage, so I hope you succeed in your project.

P.S. How is it going?

Greetings again. Little time for developing lately, but anyway did something :) I compiled a new version for the main tune removing almost all the EG effects from the song, as they were giving problems when ran on emulators (sounded differently on Oricutron and Euphoric). Maybe sounds more naive, bu...

Hi Twi... very nice test.

If I understood correctly then:

1/ Do I have to change the values sent to the EG in my 1337 tune to actual value -1?

2/ Will this make the music sound right in real machines and in Oricutron, but not in Euphoric?

More news on this, thanks to Symoon... He tested my code in another Atmos and it worked too! but not only that. Even with less cycles it worked. This is the actual code (written by Twilighte, where I removed all the waiting) for reading the keyboard (only ZXMBT=-, CTRL and ESC) is called every 4th i...

I completely overlooked the fact that original microdiscs used 3'' disks, so it might be difficult to transfer the dsk. I thought it would be difficult enough to find a computer with a 3 1/2'' floppy drive :) I clearly read this too late, Symoon. Anyway thanks for your help. These tests can wait for...

Thanks Symoon. I don't think the fact of having a disk drive changes things... I don't see how it would, but I might be losing something. Do you have a working Microdisc? Any possibility that you test the alpha version of 1337 and check a couple of things for me :) (one is the keyboard reading, of c...

Well I must admit it is 6 cycles per each of the 8 rows. But I have been reading some discussion I had with Fabrice a couple of years ago about this. And we found no explanation for this waiting time. In addition, he confirmed me that the version with just 2 nops (IIRC) worked on real hardware too. ...
