how do i play chi no rondo on the pc engine emu, Ootake? currently i have the .iso, .cue, and .mp3 files.

im geussing the game you want to play is draculax,is there are bios file in the emu?
you should check the read me file that comes with your emu and see what format the cd image should be.

Always read the accompanied documentation first, then ask questions.

i need a rom image file, but my dracula x folder only contains iso images, does anybody know how or if i convert them...

you should get a hold of medanafen-pce as that plays pc engine games in iso/mp3 format.

sure, but it'll need the bios files won't it?

Yes, all PC-Engine CD games require the System Card BIOS (v1.00-3.01 depending on the game, AFAIK)

k but, i'm still stuck on getting the rom IMAGE of akumajou dracula x, man this is killing me.

Akumajou Dracula X is a CD game, you already have the disc image. What do you need a romset for?

i have 2 .iso files. but i don't have anything that ends with .rom, .pce, and that is what ootake recognizes.

You are trying to boot a CD-ROM game, not a HU-CARD (cart; ROM image - zipped or otherwise) game. Your can't even begin to boot CD-ROM games unless you have the System Card BIOS (often syscard.pce) and the disc in the CD drive. Now, Ootake doesn't support direct disc image loading (should be fairly obvious from the first message that appears when you start the emulator), so you need to mount the disc image first to a virtual drive.

Take note that most PC Engine emulators emulate CD and the carts. Carts and the BIOS file(s) (dumped into romsets) are the only things that have the recognized PCE (or some other) file extension. No CD game has romsets (unless there were both cart and CD version released), because all the game data is on a CD already.

how does one mount the disc image to a "virtual drive"?

Well, with Daemon Tools, it's as simple as installing the program (creates an extra CD/DVD drive in Windows - hence "virtual"), and after installing, start DT (if not already running), click on the tray icon, and click on Device [X:] --> Mount Image.

Unmounting goes the same way. Then again, everything I've told you can be found in the DT manual.

Mount the CUE file, otherwise you won't get background music if you just mount the image file directly (because, it just mounts the image and not any additional tracks or sessions). If you get an error along the lines that something is wrong with the CUE file, then DT can't find the image file that the CUE is describing. If this happens, edit the CUE file by hand so that the first line (the one that deals with the disc image file itself) points directly to the file, with no paths or anything of that sort.

If the CUE file doesn't describe the WAV audio tracks at all, then you have a problem, because you'd have to type them in into the CUE file by hand.

There are other virtual drive software besides DT, so can try those as well. Alcohol 120% comes to mind.

P.S. What is the other ISO file out of the two? Or is Dracula X a 2-disc game?

as far as i know it`s one disc. the two iso files are this

Track02.iso
Track22.iso

dunno about that.

anyway, thanks for your help.
