Paging

[Tylerpsx]

Is there any documentation on how to do paging on psx systems like how they did paging for crash 1

What are you talking about? Web pages, Memory pages, Texture pages? And what is a crash 1 paging?

Considering your an elite programmer I’m suppressed you don’t know what paging spelled p a g I n g
Don’t be an asshole I’m new to this

In x86 architecture paging is when you take part of your hard-drive or mass storage in this case they did in crash bandicoot and uses it as a memory storage device so you can use more memory than the ram is in what’s known as virtual paging I know this because I used to do this when I worked at Microsoft working on the damn os’s windows 7 remember that shit I helped create that so I might be knew to ps1 architecture but I’ve got almost 20 years of bare metal c and probably more in programming languages you don’t even know
So I was trying to be respectful but If your going to be an asshole I’ll look at the microchips and engineer my own code for it thanks

Please don't talk to other members in that tone. NO$CASH was only trying to help understand your question. I assume by 'crash 1 paging' you mean the read-ahead data buffer. Basically they read data into a pool ahead of the players progress on the screen so there was no pausing and waiting for more of the level to load. It was instead loading chunks of data dynamically (which was very unique on the PlayStation 1 at the time and unheard of).

Thank you I aperciate the help I’m sorry for being an ass I’m used to talking to programmers that are high and mighty and that just set me off hobby programming and doing it for a multi billion dollar company adds a totally different level of stress especially when you don’t know how to do somthing won’t happen again. basically your saying that the cd reads data off a disc plops it into allocation and whatever was previous gets destroyed from memory based where the character is at that point similer to
Vmas in x86 (the vmas is a virtual memory access chip system in x86 that memory of the data on disc via pages in this case game objects and dynamically puts them in memory and save space by getting rid of the old crap)

No, Shadow didn't say that disc "read-ahead" is similar to "a virtual memory access chip system". Your colleagues were perhaps too polite to tell you when you made such far-fetched comparisions.

About your original question: The PSX hardware doesn't support virtual memory, so it seemed more likely that you were asking for something like using texture pages, or displaying multi-page text documents, or the like.

If i'm correct, the complete Source Code by Crash Bandicoot was released or complete documented by Naughty Dog ?
