Re: UniROM V6 - New stuff and things.

There's a datasheet for the CAT28F010N-15 flash chip, http://www.mouser.com/ds/2/308/on%20semiconductor_cat28f010-d-326877.pdf Maker code (addr 0) is 31h for Catalyst Device id (addr 1) is B4h for that chip There're also flowcharts for write/erase in there (haven't compared if/how they differ from o...

Re: PSNee further development

Thanx for the help, I will try the new code and also make some pictures for the hookup:) If you do so, please also include the signal names (GND, VDD, DATA, SQCK, etc). The "Arrow 1", "Arrow 2", "Arrow 3" etc. notation that is common for other modchip soldering guides is really ugly. It's okay for ...

It could be probably detected when knowing what flash chip you have in there. If you don't know, disassemble the card, and post a photo of the hardware inside.

Re: MKPSXISO - A PlayStation ISO Maker to Replace BUILDCD

Normally the RIFF headers are injected by the Windows operation system. For example, if you use windows explorer to copy a file from cdrom to harddisk, and then open the harddisk file in a hex editor. In fact, I think you won't even need to copy the file: You could directly open the file on CDROM in...

Re: Getting best possible RGB picture out of PS1

Whoops, 5-10 pixels is quite huge. And considering that different TVs tend to have the screen centering adjusted differently, it might well sum up to even more pixels being cut-off at the screen sides. Quite a pity that the psx kernel doesn't provide an option for calibrating the screen-centering.

Re: MKPSXISO - A PlayStation ISO Maker to Replace BUILDCD

What about RIFF headers? I don't really know what those headers are intended for, but windows seems to be automatically adding that headers to certain cdrom files (not sure which files... maybe all files with 914h-byte sectors... or so). Anyways, presence/absence of those RIFF headers might cause pr...

I really don't see a point for a GUI there. The example.xml file looks quite straight-forward. Hint: you don't need to use the "<!-- comment -->" lines in your own files, and then you could get everything down to one xml line per file. And another hint: you could type "dir" at command prompt, and th...

Re: Getting best possible RGB picture out of PS1

VGA monitors support a number of vertical resolutions: 400 lines, 480 lines, 600 lines, 768 lines, 1024 lines (the latter ones only on newer SVGAs). But they don't support TV resolutions (neither 224 lines/NTSC nor 268 lines/PAL), so you would need an "upsampler" that converts the PSX/TV picture to ...

Re: no$psx - Error "loadlibraryfailure 0000007E"

Reading directly from the PC's CDROM drive requires an "ASPI" driver. In other words: it works with win9x only. Later windows version should provide some other way to access CDROM drives, but I don't know how, and (on my win98 computer without CDROM drive) it would be hard to implement/test that stu...

Oops, yes, the "Psx Hacker Kit Beta 8 (18 in 1)" doesn't boot with any japanese kernels (even v1.0J won't boot (maybe it dislikes the changed logo, or the changed licence strings, or the homebrew exe or whatever)). The Hacker Kit has the licence string (on sector 4) replaced something saying "PSX HK...

There's a quite useful compilation disc to download (Google) called "Psx Hacker Kit Beta 8 (18 in 1)". It is patched with a custom PS logo and works on hardware, in case you want to try :) Thanks, nice to have some disc image ready for use. From what I can see, it's working on many consoles, but no...

Re: [DOWNLOAD] TMD Collection #01

Does that mean that it's possible to change the "PS" logo on the cdrom disc? And it's working on real hardware, and with all kernel revisions? I always thought that it'd be impossible to change the "PS" logo since the kernel (at least in PSone) does compare the whole disc logo against a copy in ROM,...

Just noticed that the logs (both original and CD-R) have each Point repeated three times (official specs say somthing that lead-in stuff must be on three consecutive sectors, though I think they don't say if it needs to be have the same Point value, anyways, on these discs it is the same Point repea...

Cool, that's interesting! There are some general differences between original and copy... -- Original disc uses ADR/Control=41h for Point A0h (and for the Data Track) -- CDR-R disc uses ADR/Control=41h for Point A0h,A1h,A2h (and for the Data Track) -- Original disc has Lead-in addresses ending at 07...

Chipless Modchips

Well, yes, Chipless Modchip sounds nonsense. The idea is to omit classic microprocessor based modchips, and instead output the SCEX signal on the PSX address bus, either using a custom internal BIOS ROM (which would be quite some work to install), or an external expansion ROM (eg. a cheat device car...

Re: PSNee further development

Don't forget to repair the cut trace for logging the disc's scex string. Requiring people to cut the trace or to wire GATE shouldn't matter much, or you could tell them to do either one as pleased. Simpliest would be wiring GATE to GND (I've tested that, and it works fine, but I don't know if any mo...

Re: PSNee further development

Subchannel "Point" can be 01h..99h or A0h..A2h during Lead-In, 01h..99h are for the tracks, and on a disc with many tracks those are outnumbering the special A0h..A2h values, so you should accept 01h..99h, too. Would be better to verify the 16bit CRC for making sure that it's intact lead-in data. Ah...
