Re: Mission: Paper Airplane
Can you explain the game mechanics: How do you gain speed, or lose speed? The obvious ways to gain speed would be: 1) push a button, but paper plain has no engine. 2) dive down, but that doesn't seem raise speed in this game. 3) wind hat would help you to gain speed or height, but there are no visib...

Re: 2nd Controller doesnt work?
Sorry, multiple controllers per console aren''t yet implemented in no$psx.
It can emulate multiple consoles with one controller each, eg. two player mode with link cable, but I guess that isn't what most people want : [

Re: Intercepting a crash
Crashes are routed to A(40h) SystemErrorUnresolvedException, you can hook the A(40h) function vector at address 300h (=200h+40h*4). At that point, many CPU register are smashed, but their original values should be stored on stack, you can restore them as done in the B(17h) function, that is, like th...

Re: Programming Specs feedback/question
What you are quoting there is about Memory Transfer/Fill commands, that's unrelated to texture pages (and it's a corner case that would happen only if you are (un-)intentionally using invalid parameters in those Memory commands). For the Polygon/Rectangle commands, the texture wrapping occurs each 2...

Re: SCPH-1002 disc drive voltages
The main problem seems to have been a dirty lens. That is, the spindle motor is NOT started at all when not sensing reflections from the disc. Either because no disc is inserted, or because of too much dirt. The spin-up and disc detection is now working okay... booting does still hang... I guess it ...

Re: SCPH-1002 disc drive voltages
I have replaced some capacitors. The 100uF 6V in front middle looked most visibly bulged, but replacing it didn't change anything. Some of the three 47uF 16V on left side also looked bulged, replacing them seems to have fixed the issue with my reset button (yeah! that issue was bugging me for a whil...

Re: SCPH-1002 disc drive voltages
I would expect some kind of change when the lid switch is pressed, as this tells the disc drive to spin doesn't it? As far as I remember, yes, it should spin (at least for a short moment, and then stop spinning if no disc is detected). And, as I remember, Sony didn't bother to start the spindle mot...

Re: I mode cable/software
Good that you mention those titles without game codes. I don't remember what made me think that there was I-Mode support in that Playstation the Best title, I guess that's been wrong. Also looking at PSXDataCenter, there are these three titles, all with same release date, and with variations of the ...

Re: I mode cable/software
Here comes the weekly I-Mode update: I've forwarded the HTTP messages from no$psx to real internet, and that seems to be working & stable now. I-Mode is using slightly nonstandard "GET http:domain/path" messages that need to be parsed to standard HTTP messages with "GET /path"...

Re: Foreground with transparent color over background
PS. From what I remember about what you had posted in the other thread, you did display the backgrond by uploading it from cpu (or cdrom?) to vram, such transfers are usually intended for initializing texture memory, you could also use them to initialize the framebuffer background in each frame (tho...

Re: Foreground with transparent color over background

Re: Foreground with transparent color over background
If you can't figure out what is wrong, then yes, you must use only one background. Some things that look wrong... Your png doesn't seem to contain transparent pixels, any half-decent png-to-tim converter would thus convert the solid black png pixels into solid near-black tim pixels. But anyways, you...

Re: I mode cable/software
It works!!! Doing the data transfer was quite simple, except that I totally couldn't figure out how to terminate the damn data transfer once when all data was transferred. In hindsight, it's that's also quite simple: Use message 10h/11h to start the http connection (including sending/receiving the 1...

Very good to know that the audio format is called ATRAC3, thanks! I've never heard about that format, I've looked up the wikipedia article, but I am still not sure what it is (concerning decompression speed, quality, and compression ratio, compared to other lossy formats like ADPCM or MP3). Oh, and ...

Re: SCPH-7502 problem
I still don't understand if or how you could ever have changed the potentimeter. Those things things don't change their position when you "may have touched" them. I don't trust your judgement - I am almost sure that you have never changed the potentiometer setting. Unless your definition o...

Re: SCPH-7502 problem
Did you do all those things without ever testing if the console did still work (or perhaps it even still does work)? The sled position doesn't matter, it does automatically move to innermost position on power-up. The potentiometers, there is little chance that you could change them accidently withou...

Re: I mode cable/software
Got it! It did require only a single 5-byte response on the 80h-byte stream: 84 01 73 83 57. That is, some kind of "final snippet" flag (bit7) with length (4), the actual 2-byte response (01h,73h) (which I had mistyped 01 7F in previous post). And the CRC16 (5783h) (which isn't a normal CR...
