"This new PSone featured a double speed CD Rom Drive, 2 MBs of RAM and 1 MB of VRAM"

Just like the old PS1...

This has got to be the weirdest presentation e i've ever sat through.

4000 sprites ! WHAT WHAT, no game ever released ever came that close to have that much on screen

[oliverbelen]

bro thanks so much, you actually made soft soft easy to understand

[cerveraoliver]

Nice presentation, thank you! You explained very well the Fixed Point Number limitation, which I never understood properly.
I also didn't know the 2 chip story.

I used Bleem! for Tekken 3 on Dreamcast.. It was *INSANE*

500 MIPS is the peak for the whole PSX.
"Even though it uses a relatively slow 34-MHz CPU, the processor in the original Playstation is able to eke out 220 Mips by placing much of the burden on bus and memory-access channels to enable simultaneous operation among the various functional blocks. A separate graphics processing unit brings the total processing power to 500 Mips."

125 MIPS is the peak for just the N64 cpu ALONE; the cpu is also capable of roughly 93 million floating point ops. The equivalent to the GTE in the N64 can also do more polygons. Of course, the n64 had better image quality (AA, Z-buffer etc) that killed the real world performance. This is a good lesson over why peak performance is BS.

This strategy worked perfectly on my phone

AFAIK, polygons are hardware sorted by OTAG(order tag). Also, I've used fixed point math to render 3D models and it didn't have that snap-to-grid issue. That issue is probably brought about by affine mapping looking really crazy at some angles and not the actual vertices snapping.

Presentation is ok ...BUT WHY THE LAST 3 GUYS ARE USING POTATO MICROPHONE.... WTF?

[annybodykila]

I think n64 carts got up to like 256mb near the end

[AndrewTSq]

I think 4:10 is not completely right? I thought developers went to PS1 also cause of the licensingcosts that Nintendo wanted. That is what I remember reading from magazines at the time. And I think Sony also handed out PS1 devkits for no charge to many developers.

too ahah but i watched it like 5 tis so i understand it now
