Having a lot of trouble getting this game to boot. It's hanging at the Sega logo, pretty much immediately after the main CPU starts executing code that wasn't from the BIOS. It goes pretty quickly into a trap instruction, which I feel is a sign that things have gone off the rails immediately.

Unfortunately I am incredibly lost without another emulator with trace logging to compare results against here ... so as a long shot, would anyone here be able to help with getting a trace log of the two 68Ks during boot-up for this game from a working emulator, or looking for any issues in this small amount of 68K code that I can execute? :/

Sorry to be a bother v_v;

I'll keep at it on my end as well, of course ..

Traps are being used as normal function calls on the main CPU side to signal the sub CPU. Parameters are passed via the comm regs to tell the sub to execute certain functions, then main waits to sync up with sub on completion.

Would need to look at trace past the first trap call to know what's going wrong. You should see:
- main writes function params to comm and raise its comm flag
- sub picks it up and executes while main spins
- once done, sub raises its own flag to acknowledge
- main resets its flag in response to sync back
- finally, sub resets its flag then returns to idle

Ah shoot, so I was going down the wrong tangent looking at what was causing the trap when that was actually valid.

Okay, that helps, thank you very much. I will disassemble everything until the actual stall and see where that gets me to.

Remember this table in MD work ram...

Code: Select all

;  OS system RAM assignments
;  jump table
;  vector table is 6 bytes each, but an address only needs 4 bytes.
;  Each table entry contains 2 bytes of table data and 4 bytes of 
;  address.  In other code, when you see these vectors accessed, they
;  will always be accessed with a +2, and that is why.

The startup code for the MD side sets a bunch of those vectors, including the TRAP #0.

This has become my white whale ^-^;

So I'm aware both Kega Fusion and Gens require the 'perfect sync' option to run this game.
I've set my emulator to sync all components after each component steps by one cycle.
I can confirm that's working by seeing my FPS drop from 204fps to 78fps.
My 68K core's timing passes all edge cases in yacht.txt, and though I've heard it's imperfect, I don't know what the errors in it are.
My Z80 core's timing is about 99% right, but I've heard it had tiny timing issues with a ZX Spectrum emulator using it.
VDP DMAs that stall the CPU cause the CPU to cycle step and sync every other component as well.
Doesn't matter whether I enable CPU DRAM refresh (both internal and external) stalls or not.
About the only thing I don't really do is VDP FIFO stalls, but we haven't gotten to the game drawing anything yet so I hope that isn't critical here.

I'm using jp_mcd2_921222 for my BIOS.
CPU runs at 7670454hz NTSC, MCD at 12500000hz.

Masked trace log: https://near.sh/temp/popful-mail-jp-masked.txt
Much larger unmasked log with loops omitted: https://near.sh/temp/popful-mail-jp-unmasked.zip
Much larger unmasked log without loops omitted: https://near.sh/temp/popful-mail-jp-unrolled.zip

I've confirmed the TRAP instructions are doing the right thing: hitting the BIOS ROM jump tables that then go through $fffd00+ as expected.

Stall point:

At least you don't require single cycle granularity for "perfect sync" stuff. In Gens using ~80 cycles (MD 68k) slices was enough to get all sync issues fixed less or more (at this time PC were much less powerful so doing instruction slice wasn't really possible) so don't overthink that aspect. From what i remember, this game gave me serious headaches about the PCM synchronization with the video but not so much on boot.

Call me Ishmael. :wink:

Writing zero to the wordram control reg (from either side) does not affect 2M wordram assignment. Popful has both sides write to the wordram control reg (first MAIN, then SUB) then MAIN will read back the reg to verify. If it's the wrong value, it tries again. Everything is kept in lockstep with comm sync -- no race conditions here.

Note, this becomes very trivial when you take out all the sync code...

Case 1 - assign 2M wordram to MAIN:
MAIN $a12003 := 0x00
SUB $ff8003 := 0x01
assert: MAIN $a12003 == 0x01

Case 2 - assign 2M wordram to SUB:
MAIN $a12003 := 0x02
SUB $ff8003 := 0x00
assert: MAIN $a12003 == 0x02

The 2nd case is what you're looking for. If you trace through to trap 0 : d0=0x0010 d1=0x02, you should be able to find it from there. Check out move.b d7=#$00,($ff8003) and verify the result. Should be no change.

Ishmael, thank you SO VERY MUCH!!!!

I can't tell you how happy this has made me. Definitely made my entire week.

Really, really thank you so much! I really got lost thinking it was a synchroization or trap issue.
I'm not sure what happened and where I got the idea writes to $ff8002 cleared the 2M WRAM switch.

Chilly Willy and Stef, thank you as well for your input.

Excellent :!:

Now next challenge: let's find out why sprites are invisible in all existing Sega CD emulators during the intro of Radical Rex. This one has been puzzling me for quite some time now (sorry to hijack thread :oops: )

Fuuuuuu... the bugs in that Radical Rex code, and that just in the initial loading routine. Really surprised it runs in any emulator at all. Seems like a frickin' miracle!

Well, i know that it does some quite risky synchronization at some points as it locks in emulators unless you carefully lockstep the two cpus but I wasn't aware of any other bugs...

All I know is that, when intro is started, a dma occurs to load the sprite table from word-ram but, for some unknown reason, word-ram never got initialized with a valid sprite table so an invalid sprites list ends up in VDP and no sprites are visible.

What is surprising is that this issue exists in all Mega CD software emulators (sprites are fine with real hardware or flashcarts that emulate Mega CD hardware in FPGA like Everdrive Pro or Mega SD).

Please, by all means. I have a few more Popful Mail bugs, but I should at least spend a few days looking into them before asking for help ^^;

So I thought I'd take a look and see if sprites worked in ares and ... it doesn't boot at all for me ^-^;

So at some point there's a condition to determine whether to initialize the table that ends up deciding not to do it (probably thinking it was already done.) On a whim, have we tried zero-filling all memory *and* I/O registers to both all-zeroes and all-ones?

Sour's emulators had a cool feature where it would log when a memory address or register was read before being written after boot, but it's a ton of work to add that to an emulator =(

OK, here's the bug in Ares...

In md/mcd/io.cpp, from line 208:

Code: Select all

  if(address == 0xff8004) {
    if(lower) {
      cdc.address = data.bit(0,3);
    }
    if(upper) {
      cdc.transfer.destination = data.bit(0,2); // *** should be data.bit(8,10)
    }
  }
There's probably a few other games that do word write to that register. Rex seems to work fine after the fix, but yeah, missing those intro sprites.

Wow!! You are just a saint! <3

It does indeed fix the booting problem, thank you again!
I went and audited every single io.cpp and io-external.cpp register after this one, but sadly didn't find any more fixes ^-^;

I got nerd-sniped yesterday with the SVP, but I did take a look briefly at the sprite issue.
In any case, I can confirm it's not an issue with the default RAM initialization values, but I haven't tested different default I/O register values yet.
Guessing it won't be, I imagine any I/O register of significance has been written to by the time the game intro sequence starts.

I'll try to look into it more today.
