These numbers are common for all "old" Nextgen, they are the following ones that identify the real version you own, (Avic, Pal, Israel, World, Basarsoft, etc.), but for the purposes of the Skin nothing changes, the files and folders to be changed are the same.

Golom has already answered you, but I will give you a more detailed and precise answer:

You have to delete the "save" and "ux" folders and the data.zip and sys.txt files you have and replace them with those of the Pongo Skin, the ux_additionally folder should not consider it for the moment.

You will end up with most of the menus in English and if you use a TTS voice you will have some "crippled" warning with English words read in Polish.

At this point, however, I doubt that you are able to modify the Lang, (dictionary.lang), and the Voice, (dictionary.voice), so you should follow my advice to ask for help from some Polish user who already has them, you will be able to broaden your knowledge later on calmly, then if you want to try to do it all by yourself, go ahead ...
