Re: v15 & new recompiler update

Mine is also 7.3.0.

Code: Select all

gcc version 7.3.0 (Gentoo 7.3.0-r3 p1.4)
My work laptop also uses the same version on an internal distro.

Re: Speed timings for emulated hard disks

PCem is not just a wrapper or virtualization software, so accurate timings make total sense. Also, inaccurate disc access times and/or behavior are known to cause problems in various platforms, for example see "5.0-2431 - DVD Timing Accuracy Upgrades" in this report: https://dolphin-emu.org/blog/201...

Same behavior here when using a debug build on x86-64 Linux. I can't test on x86-64 Windows.

Re: v15 & new recompiler update

To make the dynarec optional, you can remove CPU_REQUIRES_DYNAREC from your CPU in cpu_tables.c. Not usable but you will be able to tell if the issue is with the dynarec.

Re: Using special machine types

Between machines with similar features and performance, the difference will mostly be related to nostalgia and preservation. Sometimes there are bugs or quirks (real or from the emulation) that will make software work in one but not in another.

Re: Are ISO+OGG (or similar) CD-ROM images supported?

CD-audio also has very basic error correction (most data tracks use more of the sector for extra error correction/detection).

Re: [Patch] Packard Bell Legend 300SX

Thanks for the tip, leilei! I've been using ImgBurn for regular CDs and Alcohol 52% for titles with copy protection. In this case, however, there was no difference when using different software. I'm going to set up a 32-bit environment to see if this alse happens with the 32-bit recompiler.

Re: [Patch] Packard Bell Legend 300SX

It's an obscure 1995 magazine CD from my country. I've been dumping everything in my possession lately. The ISO is 134MB bzipped but just running the .exe file without any data is enough to trigger the crash. I believe there would be no problem in distributing this specific executable for you to test.

The crash upon entering the BIOS seems to be fixed, but the one from the log I just posted still happens. I'm guessing it's completely unrelated to the cd subsystem, sorry!

I start the machine it post but when it goes to boot it crashes. It seems to happen when certain cdrom images are mounted at boot. I can confirm that this happened to me some time ago with the install CD of a linux distro, mounted at POST = crash in various AMI bioses for Pentium. Forgot the report.

[Patch] Xi8088 - GPL XT system bios

The Xi8088 is a great project by Sergey Kiselev to build a XT-clone, I've built it myself along with the other boards by Sergey and they work great. The system is a XT along with some AT and PS2 features like PS/2 mouse, AT RTC/NVR, two PICs, etc. More info in http://www.malinov.com/Home/sergeys-pro...
