Would be nice to have a version showing speed from different area : ROM / RAM / comm registers... :) You might add more speed tests for the sub cpu showing the speed in program ram vs word ram vs communication regs. Here's a new version, now can select different areas: Also sub-cpu now shows correc...

I made it from VRAM... (filled all vram with code: add_tacts add.l d2,d0 bra.s add_tacts). also 'rte' after v-int, was replaced with manual returing (in 50% happens returning to $c00002 but with first opcode?) test non-repeatable , goes only 2 seconds: , after I load numbers to vram to show result. ...

Got 7,645 by code executing from a12010-a12013 (scd registers area):
also tested $200000 (sram) and $600000 (scd word-ram) - 7,525 same as rom.

"Ram" version:

Tested - yes, it even more slowly:

Test goes 1 second, counter - 50 vblanks for PAL, and 60 vblanks for NTSC. Code executed from ROM.
About RAM I did not know, maybe I will do this too.

Yes, it's count number of cycles for 1 second, then repeat again.
for gfx processor it's repeats 128x128 conversion in a loop.

Or get track time, and use it as counter to start next track.

Still boils down to the same case, you just need a random number when you're going to decide which track to play next. No, I not just need a 'random number'. I need to know that one track stops playing, to start playing next. How can I do it? EDIT: also wait, seeing what post you quoted, are you co...

No. I don't need to start play random track once\repeated\or from random track to last track.
I ask for random-B mode (when track ends, next is random) - infinite disk play.

A - play from current track to end of disc
B - play current track once
C - stop playing
X - show current track info
Y - play current track repeatedly
Z - pause/resume
START - check disc

How can I make "play random track?" (same as RANDOM-B in Japanese bios player?)

On Mega Everdrive (with 16-bit sram) most(or all) byte instructions doesn't work on odd addresses.

Here's my compilation for r57shell's player: Tracklist: Vectorman 1, Earthworm Jim 2, Doom Troopers, Comix Zone, Dune2. gems_compilation_wip.rar Some bugs of GEMS_Player.bin: Some wrong in rom header, code starts from (0x1F4 instead of 0x200). When you play combined song (example: DT: Nero) , and if...

Anyway, there is so many emulators, and no method to get timings of code chunk :( Gens standart debugger shows how cycles each command takes. ) hotkey 't' is step into. O_o ? Did i put that feature ?? I only remember about execute 1/10/100/1000 instructions shortcut but nothing about cycles... Yep,...
