* All of them access the same register block. VFPU have really weird register mapping where first character is access way, first digit is register block number, second digit is "horizontal" number of register in block, and last digit is vertical number of register in block. One block is 4x4 size, and there is 8 blocks (0-7). Looks like VFPU registers are xxx414DE0 - xxx414FDF, but its unconfirmed for now. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 11:32, 23 June 2023 (CEST) | * All of them access the same register block.

** Ok, regs are there. Confirmed in instruction decoder. Starting at 414DE0 one block is 0x40 long, so next block is 414E20, etc. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 11:41, 23 June 2023 (CEST) | ** Ok, regs are there.

<br> [https://anonfiles.com/e648dfyezd/HeapDirectMem_0_3_200000000_131072KB_7z Here's a backup of the entire heapmemory file.], The PC's and RA's current values are 78 87 81 08. And the V0 and (S713 maybe? I don't remember but I think it was this one) both have a value of 00 00 54 98 --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 21:29, 22 June 2023 (CEST) | |||
