Good to see some old school stuff getting update

I was wondering if it will support the small late model PS1 since they do not have serial port

It's Refreshing to see that people are still working on PSX Hacks and mods. More than not in a scene like this, people move on after console life. I don't even own a PSX anymore, but I would pick one up just to use one of these. Seeing newer technology used to hack an older console is just plain awesome.

Hopefully, that's all I have left.

Well I have a older one and it boots but cd drive shot
but that slim of mine still works

nice to see this, i still got a old fat ps2 with a broken laser and a small white one that is begining to have difficulty reading cd's.

hope it can be modded on all version of ps1. PS1 lasers are hard to come by now, well in my country that is

Good, new life to my old 6 consoles

This is great and I fully support it. However, I do have one tiny nit-pick:

emulators are slow, somewhat poorly coded and are not 100% accurate. You can not emulate hardware in software 100%. This is impossible.

Almost this entire statement is wrong in some way. Emulators are comparatively slow in terms of how much processing power you need to emulate a different processor, but the PS1 isn't exactly lightning fast, either. You can get full-speed emulation on a 10 year old PC. To say that it's "slow" implies that modern machines can't run games full speed, which isn't true.
The "poorly coded" remark is just plain wrong. Sure, the emulator might not be 100% accurate but that has nothing to do with how "well" the emulator is coded and everything to do with the fact that the difference in processing power it takes to go from 95% accurate to 100% grows exponentially.
You can emulate hardware in software 100%, it's definitely not an impossibility. The problem is, as I've alluded to above, you can generally get to about 90% accuracy (Read: Compatibility) with about 10x the processing power of the original hardware. From there, each 1-2% effectively requires double the processing power again. If you look at emulators for older machines, particularly the popular ones like the Atari 2600 or the Nes, they are very nearly perfect (cycle accurate) and given enough time, the PS1 emulators will be the same. We're currently at about the level where we can get near-100% accuracy of a SNES, so the PS1 isn't far behind (This decade, probably). That said, I'm not aware of any PS1 games that absolutely cannot be played on an emulator.

However, as I've said I love the idea of this project and I fully support it, but don't dismiss emulators so readily - after all, this product is designed to extend the lifespan of the original hardware by sparing the CD drive. Well, what about the rest of the hardware? Eventually it WILL die, it might take decades but it will. When that happens, Emulators will be there to save the day.

this blows up PS1 sales

i wonder where will we mount sd card reader and hacked os thing. I hate soldering tiny solder points.

i think this is pretty cool.especially for ps1's that have a broken laser etc. with mulitman and psp i can play so many titles digitally with psp and physically with ps3. Having said that i still have my whole library of playstation 1 cd's and I haven't had to replace them worse case scenario i could just burn a backup for ps3 or make an eboot for the psp. Realistically your playstation 1 will die before any of your actual games do. But for people who still sport their retro gaming this just might be a nifty device
