NO$PSX Feature Requests

Post by Shadow » August 13th, 2017, 3:57 pm

NO$PSX - Highly Requested Features
:null:
  • Have the ability to debug CPE files that have been compiled under Psy-Q with the '-g' command (via CCPSX) which will use the Psy-Q *.SYM (symbol files) to debug the source code in real-time (exactly like a DTL-H2000) [Requested by: Shadow & LameGuy64]
    :null:
  • Display 'cop2' instructions in the debugger as GTE commands (RTPT, NCLIP, etc) as well as displaying 'cop2' registers as regular r0-r31 registers or 'C2_*' macros that represents the register's purpose (C2_XY0, C2_Z0, etc like when writing GTE routines in assembly with the macro headers in the official development kit) [Requested by: LameGuy64].
Development Console: SCPH-5502 with 8MB RAM, MM3 Modchip, PAL 60 Colour Modification (for NTSC), PSIO Switch Board, DB-9 breakout headers for both RGB and Serial output and an Xplorer with CAETLA 0.34.

PlayStation Development PC: Windows 98 SE, Pentium 3 at 400MHz, 128MB SDRAM, DTL-H2000, DTL-H2010, DTL-H201A, DTL-S2020 (with 4GB SCSI-2 HDD), 21" Sony G420, CD-R burner, 3.25" and 5.25" Floppy Diskette Drives, ZIP 100 Diskette Drive and an IBM Model M keyboard.

I've been asking for this feature several times over the years. I hope No$psx in the future can emulate sio parallel port. This will allow running games which attempt to retrieve files from a PC via PCOpen/PCClose etc.

2nd controller support would be very nice? :/

Wireframe rendering as a debug feature is really needed.

Real-time debugging support on a real PlayStation would be awesome. At the moment, I think "Upload a PS-EXE" only uploads to the PSX's RAM. It doesn't actually allow you to debug the program running I don't believe.

I'd also really like to see the GUI re-designed to something more like S.N System's design.

There is a major bug in NO$PSX V2.0 which is that the TOC (Table of Contents) is not being updated correctly: http://www.psxdev.net/forum/viewtopic.p ... 158#p14340

Uploading exe to Xplorer / Xplorer FX, no matter what original rom version they had, worked flawlessly and the upload is damn fast and stable compared to X-killer. :clap
Great work with that stuff, thank you very much for this. :praise
Maybe Caetla roms support could be considered in later release ?

being able search for ascii strings and for values changed over a step would be incredibly useful imo

Memory breakpoints on read/write would be heaven.

Have a memory usage indicator, so it is easy to see the Main RAM, SPU RAM and GPU RAM usage levels.

Whenever I boot up the PS1 BIOS on the latest version of "NO$PSX", it freezes on the Sony Computer Entertainment screen. Looking in the TTY command logs, there seems to be some interferance with the CD-ROM DMA channel by the looks of it. I'm using the latest version of "NO$PSX", version 2.8 to be exact and not the gaming version.

Allow disc swapping (open/close drive lid WITHOUT RESET), like DuckStation.

I'd also like to know if anyone has gotten this working well with wine. Most games encounter a 'mem full' error when using wine to play them.

Disabling the "Autostart CDROM" checkbox (in lower-left of the Open file dialog window) when loading the CDROM-image should work.

I've never heard about that problem. As far as I know, no$gba is working fine with wine, and no$psx should require even less memory (compared to no$gba in NDS mode with huge memory mapped NDS rom-images).

Does the error screen look as if it's generated by no$psx, or by the OS utself? And does the error message really say 'mem full'? I can't find any such message in my source code.

And when does that error occur, immediately after loading the ROM-image, or after running the emulation for some minutes? There are some logging functions in no$psx that might allocate more and more memory over time (for TTY messages and for the most recent video frame in the GPU/VRAM viewer, the latter can be a problem with homebrew code that doesn't do "swap buffers" to indicate the begin of a new frame).

PS. If it's logging related: does it also occur in gaming version? And, you have the most recent no$psx v2.1, right?

Thank you for the response. I will check with the memory error and let you know.

I setup no $ psx emu v2.1 with lutris (on linux using a different wine version from lutris) and it works great now, including the swapping of discs without reset. Thanks a lot, now this can be my main emulator for testing things.

I was wondering if it would be possible to add even larger fonts? I also can not find a way to increase the font size for the debug tty messages window.
