Do you have any information how fast the DSP is? Unfortunately, I did not have much information on the 3DO architecture. Some information from SDK, some from 3DO patents, some from my own architecture study. I think the DSP core is faster then ARM on operations with short data types and I know that...

Jones I think the some image postprocessing or graphics FX can be realised on DSP. MP3 processing is problematic, becouse decoding process need a lot of floating point math operations wich not presents in 3DO hardware (only 32 bit fixed point). But many audio processing algorithmes can be realised ...

Jones, the 3DO DSP has all ability to process audio. In 3DO SDK, there is a part of docs and samples which explains how working with MIDI sequences. And even more, DSP can be used for fastest user data processing. This is a very flexible device.

It will be just fine! My guess about the copy protection has not been confirmed accurate facts, only indirect evidence. History requires accuracy!

It looks great! :) So it uses full hardware 3D acceleration with texture mapping and lighting effects at 300 polygons, right? No, 300 polys per scene, but actually rendered much less - about 150-200 polys (some polys is backface, so skipped). Did you write that program in assembler code? No, in C l...

Does it use any 3d acceleration from the CLIO/MADAM custom chips, or is it purely software based rendering using only the ARM cpu? Yes, this simple 3D engine use 3DO hardware to render scene (3DO math accelerator uses also). I try to write my own engine and I learning to 3DO architecture in this pr...

Do you still manufacturing ur IDE adapter?? and how much it cost :) iam thinking of striping down an fz1 and and put it in a pc case and convince myself i own a 3DO BLASTER when iam playing with it. now thats a cool project :wink: I dont manufacture this adapter, I just buy this cool stuff from MNE...

How would that microcontroller react to your IDE adapter? Would this copy protection device make it impossible to use your IDE adapter with Goldstar 3DOs? My version of IDE adaptor only for FZ-10. So I dont know how microcontroller shall react to external CD-drive in Goldstar 3DO. I think not only ...

I think why Goldstar used copy protection in its console - it's because they were the manufacturer of 3DO software. In this way Goldstar protect their business. It is difficult to say what type of protection used in the console. The patent describes the use of a microcontroller, which decides the le...

Hi, everyone! This person, who told about copy protection in GDO-202P, is I am. I want to say a few words about the console GDO-202P. Sorry about my english.:oops: In Russia we have several models Goldstar 3DO - 101 & 202 models are mostly common. We know 202P as problematic console (all of CD-Rs wi...
