Gens4All with Z80 Emulation

[Ian Micheal]

Don't feel afraid to reach out
Could have saved you an hour
https://github.com/mrneo240/openmenu/bl ... font_bmf.c

I hope to see sneak peeks or such on the game! Great to see you aren't leaving but rather refocusing into a single thing.

The timestamps on my backups for my BMFont code start in 2017. I guess I could've saved you an hour if I posted it.

I think I'm going to make a thread to post about progress. Having people interested should help motivate me.

Problem only happens on rca leads like i said... It works perfect on vga since i dont use rca leads it's not a problem for me but users..
the emulator does not crash and you can go back to the menu there is no sound ether on rca leads when this happens, other games works fine just a few that do this.. The problem game as i said this happens on few others..

Huh. I guess the issue is probably with the emulator core, then. I have no idea how the cable type could cause that. If I manage to get my setup changed so that I can test on NTSC easier, I might go back and take a look at it.

debug loading the rom now

now this is what happens yet it worked the other day and i made a video on hardware never had this type of thing before where it worked now it does this every time

It looks like the watchdog is timing out while loading the ROM? I thought I paused the watchdog while loading?

Er, I can't find the pause call, so I guess not? I'm surprised people could load larger ROMs at all from disc.

Here's a quick version 4.2, which pauses the watchdog when loading ROMs. I didn't include the full source, just the single file modified file compared to version 4.1.

No problem with the core loading the game it's just from a cdr

[TapamN]

It seems like it's still getting stuck in cdrom_exec_cmd somehow. Alright, here's a version with the watchdog disabled. It will probably end up just freezing.

New version still did this but again works from loading the rom f/pc with a coders cable ?

Still saying this OUTPUT:> kernel panic: Watchdog timeout for a cdr but works on GDEMU with out trouble ? Seek time? works on dreamshell as well.. Just not a cdr

[TapamN]

Yeah, it occurred to me a couple minutes ago, even before I read your post, that I disabled it incorrectly. Here's attempt two. I even tested and infinite loop this time.

Actually, it looks like my attempt to disable it only during loads didn't work because I made the same mistake?

I'll make a CDR version with this new binary w/ padding shortly. I'm also going to chop extra "_"'s off the filenames.
