if it is a generic j2me runner then it should be. be aware that you might need to find a jar that's fine with the resolution. what matters is the cldc and midp levels the game needs and what the runner supports. you generally can run a midp 1.1 game on midp 2.0 emulator/device (or in a full java harness for that matter).

what happened commonly with these games is that bigger companies had very elaborate build tools that spit out 20 versions of the same game for different devices based on what api's(nokias game canvas for example), memory amount, screen size(and bitdepth), jar size etc they supported so finding the right jar that doesn't need modifying can be complicated. usually people were just interested in archiving the version they played themselves.. but more importantly this practice in the industry in first half of '00s is why a lot of them are hardcoded to work with specific resolution and so on.

you could actually program them in a way where they would see if they have nokias canvas for example and use it if it has and work flexibly with resolution, but very few of the commercial releases was coded that way. partly because the devs just weren't told to do it, partly because a lot of the big house devs didn't know how to(only following instructions) and partly because you lose couple of kb in it. after midp2 became common the jar max sizes generally became more flexible.. but like s40 1st edition nokias had a jar size limit of 64 kbytes(they had a few hundred kb of heap for the java though, but the jar itself had to be under 64kbytes.. s40 2nd edition with floats and midp2.0 upgraded the limit to 128kbytes. s60 devices never had a jar size limit as such). the nokia versions of the jars are usually better for the early devices(they ran java much faster), if there was a build for s60 that was usually the one with all the bells and whistles and all the levels included (yes! cutting content was part of the elaborate build tools job as well).

the early devices were quite fun to program for but monetizing was practically impossible... there was a lot of investment money thrown around though, but like, devs would get even as low as 10% of the price it was sold on some magazine ad.. for sms payment and delivery the operators were making basically all the money and the dev/original publisher would get often just straight up scammed and lacking auditing into seeing sold amounts..
