The USB 1.1 loader for the CD-ROM was tested today.

It is extremely slow at the moment, but this is because it is being loaded over USB 1.1 (approximately 12Mbits/second (1.5 megabytes)) from a PC. The PlayStation 1's CPU access's the data by in blocks of 2048 bytes at delay of 0.5ms. This is really fast. However, the DMA (Direct Memory Access) pauses for the next block at a delay of around 300ms +- 0.5ms.

We are still working on the speed, fixing bugs and working on the OS (psiOS). Expect it to load from an SD card very soon!
