Re: UniPCemu emulator releases

Two small updates fixing some bigger problems(like Megarace now fully working, with(CD-ROM version) and without CD-ROM(demo version running from CD-ROM(.iso createn with the demo files on it) and harddisk): UniPCemu_20171214_1304_PSP.zip Changes: - Improved result phase of ATAPI commands to be more …

Re: 80386 emulation vs Megarace cutscenes?

It seems that my most recent changes have fixed the Megarace cutscenes(which are mainly CD-ROM bugfixes and setting Megarace up correctly(to use the correct Sound Blaster IRQ 5/DMA channel 1 settings). With those changes, Megarace seems to work in all configurations, both demo and actual game alike …

Re: 80386 emulation vs Megarace cutscenes?

I've just tried copying the CD-ROM disk contents containing the demo to the hard disk within the emulator, then extracting them using WinImage(harddisk) and WinISO(CD-ROM) and used WinMerge to compare the files. Both check out to be identical? So the CD-ROM emulation itself is working properly( …

Suddenly can't edit posts anymore?

in Milliways
For some strange reason, just now I can't seem to edit my own posts anymore? The edit button is gone and trying it manually using an url (e.g. http://www.vogons.org/posting.php?mode=edit&f=9&p=634629 (I've just taken the f parameter and the p value from a jump link on one of my posts) ), it gives me …

Re: UniPCemu emulator releases

A new UniPCemu release, with a big IPS clocking optimization improvement and other slight optimizations: UniPCemu_20171213_1415_PSP.zip The Windows and Android builds can be found at the itch.io page. Changes: - Adjusted the VGA 28MHz clock to 28.322MHz(previously 28.321MHz). - Optimized BIU …

Re: x86 software vs hardware clocks

Those clocks are already modified. I've improved IPS clocking to loop pending BIU cycles when in that mode(exception is when it's not spending cycles due to hardware waitstates(resulting in an infinite loop otherwise, hanging the app)). This causes the emulator, when in IPS cycle mode, to run at …

Re: x86 software vs hardware clocks

Just adjusted the VGA to use 28.322 and 25.175Mhz. The rest is unchanged(ET3/4K still Dosbox-X clocks). Anyone figured out the exact 8/16 clocks of those? Are the Dosbox-X clocks already accurate? Or do they need adjusting to be using the clocks in the photo's? I see 6 onboard clocks, but 16 …

Re: x86 software vs hardware clocks

So, the ET3000 has the following clocks(converted from Dosbox-X VGA_tseng.cpp): 0:CLK_25=>25750kHz(UniPCemu: VGA standard clocks=25175kHz) 1:CLK_28=>28322kHz(UniPCemu: VGA standard clocks=28321kHz) 2:32400=>32514kHz? 3:35900=>36000kHz? 4:39900=>44900kHz? 5:44700=>44900kHz? 6:31400=>32514kHz? 7:37500 …

Re: UniPCemu emulator releases

A new UniPCemu release, with some slight improvements and bugfixes: - Improved higher frequency clocking with slower 14MHz and lower hardware, allowing increasing the CPU clock without making those hardware heavier(the only exception being video clocking(at non-14MHz, so everything except 14MHz EGA …

Re: Finding bugs in 8086-80386 emulation core?

Just did some more tests on the Caps lock issue. It seems that it affects Num lock and Scroll lock as well. Pressing any of those three modifier keys makes the BIOS send a 0xED(Set LEDs) command, but never the second parameter required to finish the command? That causes the PS/2 keyboard controller …

Re: 80386 emulation vs Megarace cutscenes?

I've just tried the old hard disk based copy of the Megarace demo(instead of the CD-ROM version), with the minimal parameters(Just Sound Blaster sound and subtitles enabled, all other stuff(like HIMEM.SYS RAM etc.) is disabled). It just runs the cutscenes without problems? So could that mean it's …

80386 emulation vs Megarace cutscenes?

For some reason, the 80386 emulates fine, but the megarace cutscenes stopped working at some point? BIOS and testsuites give no problem. The Sound Blaster isn't giving any sound for some odd reason? Can a problem with the Sound Blaster 2.0 emulation give problems with the Megarace cutscenes? The …

Re: Windows PPP server listening on TCP port?

Is there e.g. a winpcap-based server that listens on a TCP port for incoming connections, transmitting it's data(converting between slip and raw packet data transparently) and sending/receiving said data to the network using the pcap functionality? So you can open a connection on said TCP port( …
