@walkero @TheMagicSN
Thank you. It is very motivating to hear this from you

I still need to test a few things and test. @Maijestro is helping me - thanks

If anyone supports HunoPPC and has access to its FTP the file made of my test version is in my home directory.
This way I can also support HunoPPC and thank him for his long-term work with AOS4 and motivate other people to support him
https://ko-fi.com/hunoppcThe current version of Doom64EX+ under AOS4 is updated. It works most of the things that are in the SDL3 version.
It uses the current file and full OpneGL is enabled, along with texture combiners.
Instead of FMOD it uses fluidsynth, the SDL3 replacement is SDL2+GL4ES.
Doom64Ex+ uses WAD from the 2020 "remaster" version. Many people believe that the open source version of Doom64EX+ is even better than the original version that was released.
To play under the game port on AOS4 you need the original WAD from this version.
Currently available for purchase for $2 on GOG

For those who are MorphOS users - @BeWorld has released its very good port to this platform and the WAD file will work on it.
https://www.morphos-storage.net/?id=2402459 Let's start with a small thing - Doom 64 is NOT another port of the original that other consoles of the time, such as PlayStation or Sega Saturn, got. This is another installment, the existence of which most gamers may not have known or may have heard a handful of information from even a neighborhood buddy equipped with a Nintendo 64 with a cartridge with this title.
The first impression is... electrifying. The soundtrack of the game strikes the ears. Those tuned to the next, filled with the essence of rock music melodies must expect gloomy, atmosphere-filling ambient, which can instead settle those identified with PSX or Saturn's Doom. The locations are covered in gloomy colors, and this time there is no question of more availability of bright rooms. The composed setting creates a slightly horror-like atmosphere, giving a sense of emptiness and loneliness in the fight against our enemies.
The remaster of Doom 64 includes an additional campaign, The Lost Levels with the content of 7 levels (1 of which is hidden). You gain access to them after completing either the main storyline or Hectic levels. The Lost Levels is a chapter exclusive to this remaster and bridges the gap between the old (Doom/Doom II/Final Doom) and new (Doom (2016)/Doom Eternal) installments of the series.
Doom 64 is a title that will delight the younger as well as the older generation of gamers. Those who know the previous installments from cover to cover will be excited by the new challenge.
So much for the rewriting of history
