This is a simple memory viewer for the PlayStation.
It shows you what is contained at the desired memory addresses in a way similar to that of hex editors.

Obviously it is not as straigthforward to use as similar programs for general purpose computers because the PlayStation lacks a keyboard.
Also, *remember* that reading certain memory areas will crash the PlayStation hardware, and if that happens the only thing you can do is to reset the console.
See "Surefire Areas" below for areas which surely won't crash your hardware.

At start, the memory viewer will begin viewing memory at 0x80000000 (start of RAM),
the resolution will be 640x240 (low-res) and the Go-Address will be 0x80000000.

Terms:
Go-Address				The address that will be used for the
					"jump-to address" operation

Control:
UP					Decrease current address by 0x10
DOWN					Increase current address by 0x10
LEFT					Decrease current address by 0x100
RIGHT					Increase current address by 0x100

L1					Move to previous location in Go-Address
R1					Move to next location in Go-Address
L2					Move to first location in Go-Address
CROSS					Increase nibble at current Go-Address location
CIRCLE					Decrease nibble at current Go-Address location

START					Jump to Go-Address, 
					i.e. make the Go-Address the current address

SELECT					Switch between hi-res and low-res mode
					Hi-res mode: 640x480
					Low-res mode: 640x240 (default)
						
Surefire areas:
0x80000000-0x801fffff		PlayStation RAM (2 megabytes)
0xbfc00000-0xbfc7ffff		PlayStation BIOS ROM (512 kilobytes)

Example of setting a Go-Address and jumping:

Imagine that the current go-address is 0x80000000 and we want to jump to 0xC001D00D.
NOTE: A nibble is 4-bits long, and each digit in a hexadecimal number is a nibble.

- Move to the first location in Go-Address -> L2
- Increase the nibble at current Go-Address location until it is 0xC
  -> as its current value is 0x8, due to the current go-address being 0x80000000,
       press CROSS 4 times
  >> after this operation, the current address is 0xC0000000
- Move to the next location in Go-Address -> R1
- The nibble at this location is already 0x0, so move to the next location -> R1
  >> after this operation, the current address is 0xC0000000
- The nibble at this location is already 0x0, so move to the next location -> R1
  >> after this operation, the current address is 0xC0000000
- Increase the nibble at current Go-Address location until it is 0x1
  -> as its current value is 0x0, press CROSS once
  >> after this operation, the current address will be 0xC0010000
- Move to the next location in Go-Address -> R1
- Increase the nibble at current Go-Address location until it is 0xD
  -> as its current value is 0x0, press CROSS 13 times
  >> after this operation, the current address will be 0xC001D000
- Move to the next location in Go-Address -> R1
- The nibble at this location is already 0x0, so move to the next location -> R1
  >> after this operation, the current address is 0xC001D000
- The nibble at this location is already 0x0, so move to the next location -> R1
  >> after this operation, the current address is 0xC001D000
- Increase the nibble at current Go-Address location until it is 0xD
  -> as its current value is 0x0, press CROSS 13 times
  >> after this operation, the current address will be 0xC001D00D
- Jump to Go-Address -> START
  >> The current address is now 0xC001D00D
