NES files store game ROMs for Nintendo NES gaming console (known in Japan as Famicom). NES files can be opened using dedicated emulator tools available for desktop and mobile devices. In Poland, NES console clones were were knows under the name “Pegasus”.
File with an APK extension contains a compressed archive with an application, game or some firmware for the Android system. It cannot exceed 100MB – such restriction is being implied by the Google Play store.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the NES file after converting to APK may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from NES to APK to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting NES to APK does not meet your expectations, you can simply try to find on the Internet a different version of your file in NES format, properly converted to a APK file by someone else. If this fails, use the information provided in the further part of the website.
Unfortunately, if after performing the two previously described steps (trying to find your NES file converted by someone else, and the attempt to convert it to APK on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the NES file in its original format (without conversion to APK file). Such a solution will be difficult to implement, but it certainly will give the best result.
