It emulates the NES quite well with 100% speed on the games that it does emulate on the 33MHz Playstation.
The mapper support is alright, and after all, a $5 PSX + $5 modchip is a lot cheaper than a NES
What you will need:
- The zip file from the download page
- a CD burner
- a Playstation or PS2 that is already capable of playing games on CD-Rs (ie. a PSX with a mod chip, boot disc, etc...)
- Any burning program that can burn standard ISO images. I recommend CDRWIN or Nero.
Directions for imbNES v1.3:
1.) Download imbNES v1.3 from the 'Downloads' page.

5.) Once you've added all your ROMs, you can manipulate the list to get it just the way you want it. At the very least, you'll probably want to sort the list alphabetically using the "AZ" button. ()
6.) When you're done making your ROM list, click the 'Build imbNES ISO' button () in the lower left corner. Then pick the appropriate license (USA | Japan | Europe), press 'Build ISO', and choose where to save your ISO image.
7.) Once the build process if finished, you can close rombank.exe. Now you're ready to burn the CD image that was just created...
Optional: If you're worried about wasting CDRs, you can test the image you just made using the PSX emulator PSXeven which you can get on the downloads page. (BIOS not included)

Using It Might Be NES:
After the splash screen, a list of ROMs on the disc will be displayed. Use the d-pad to navigate through the list to find the game you want to play. You can use the L1 and R1 buttons to page up and page down through the ROM list quickly, or press L1+R1 to go to the middle of the list.

When you're all ready to play, just press start and enjoy! To return to the menu from a game, press L1+R1+Start+Select.
