Re: Black PlayStation ? (versus PSXSERIAL)

1) When Sony decided to launch a homebrew development platform for the PlayStation in 1996/7 (which later became the Net Yaroze), why did Sony demand that users had to purchase an entirely new black PlayStation, rather than simply creating a cheap PSXSERIAL type cable (and disc) which could attach ...

Re: Reverse Engineering the PSX Copy Protection (Wobble Groove)

For what it's worth, the "Modern Vintage Gamer" posted a video about PS1 security onto YouTube earlier today, and he mentioned at the ~6:15 mark that there were certain CD writers that could actually write the wobble sectors once flashed with custom firmware - followed by a photograph of a Plextor 1...

SCPH-7502 = Better graphics ? ("PS1.2")

I've been re-reading some old issues of EDGE Magazine (UK), and – according to reader correspondence in issues 67 & 68 from 1999 (see link below) – some people were claiming that newer models of the PlayStation / PS1 (presumably the SCPH-5552 or SCPH-7502 ?) featured slightly better graphics than th...

"Forward compatible" PS1 games w/ 8MB RAM?

Just a random thought – given that the PS1 can technically address up to 8MB of RAM (and the well-documented SCPH-5552 mod proves that it's possible to physically add this memory to an actual PlayStation), wouldn't it have been cool if some later PS1 games (such as Tekken 3) had been made "forward c...

Re: Black PlayStation ? (versus PSXSERIAL)

This is the cartridge I'm talking about I've also seen that PSY-Q magazine advert before (along with a similar piece of kit for the Sega Saturn) After boot, it's a waste of time checking region/wobble, but later games do (Final fantasy) rechecks for the wobble signal. I don't totally agree that it'...

Re: Black PlayStation ? (versus PSXSERIAL)

1) Yes, and SN. Systems actually made their own professional debugging and development cartridge to replace the DTL-H2000. This is that blue cartridge that looks exactly like an Xplorer/Xploder. It has a yellow PCB inside with a coin battery and some Altera CPLD's. This never took off though, and S...

Re: Black PlayStation ? (versus PSXSERIAL)

Thanks for your responses. A few other thoughts:- 1)I agree that nobody would pay $1000 just for a serial cable and a few discs, but theoretically I would have thought this simpler kit (without a black PlayStation included) could have been sold for a lower price point of around $50 instead (and perh...

Black PlayStation ? (versus PSXSERIAL)

Hi all. I've created some basic demos using the PSY-Q and Yaroze dev kits, and had a few questions that I was hoping somebody could kindly answer for me:- 1) When Sony decided to launch a homebrew development platform for the PlayStation in 1996/7 (which later became the Net Yaroze), why did Sony de...
