I recently acquired one of these and I have been to Chris Covell's page about this unit, but I want to know if anyone here can answer the following :

1. this unit seems to play cartridge games at a slow speed. is this normal?
2. what do I need to convert .NES format games to work on this unit?
3. what memory mappers does this unit support?
4. does there exist a way to use regular NES controllers with this unit?

any help is appreciated!

1) Maybe?

2) http://www.zophar.net/utilities/nesutil/qnd.html

3) 0,1,2,3,4,9,66 + hacks

4) Does there exist an adapter? No. Can there exist an adapter? Yes.

thank you for the reply. I usex qnd but every time I try to conver games it says it can create the file and I am using windows XP. what hacks are available and where may I get them?

RGB_Gamer, it's possible that your PCJr is one of those elusive PAL variants that runs games at 50hz. Most/all games should run at full speed if the PCJr is an NTSC version.

There are hacks available here: http://www.chrismcovell.com/drpcjr/patches.html

You can make a controller adaptor using this document: http://www.chrismcovell.com/drpcjr/PCJrControllers.txt

I don't have any pal carts - they are all NTSC

Pal version weren't even optimized most of the time...they would stil run slow.

At least the music usually.
Megaman 2 for example. They didn't even adjust the pitch, as far as I know.

They adjusted the pitch in all Mega Man games, even if this introducted sound effects glitches in the first two.

Oh, I didn't know it was like that. I guess, I was wrong then, with the pitch not being corrected.

so does anyone know how to play ntsc games on the dr pc jr at full speed?
