    Yesterday I got the new microSD and in the evening I copied them all and I started the test, for now only of the first level for each one.
    As expected smooth gameplay and, except for H.R.2, no slowdown.
    Only Doom Earth starts with a texture glitch, when the character looks at the wide horizon (caused by insufficient RAM memory available, I suppose): besides, I couldn't find the path to finish the map.
    To my great satisfaction, I notice that the save function, unlike DS Doom (when using vanilla wads), always works perfectly, but it loads from the beginning of the level, anyway keeping weapons and items already collected.

    In the pictures, these wads are tested on slot2 of my pink DS Lite and launched via YSMenu (r4i software) with gbaframe.
    Looking forward to test, if and when It will be, Freedoom1/2 and Community Chest Series,
    or other classic wads, old or new,
    and fatten this fantastic Doom collection.

    Thanks again, american friend.

    P.S.
    Following my first impressions, I have come to the (perhaps obvious) conclusion that the best and most suitable wads for the gba are those with small to medium sized maps, mostly narrow and collected environments, with corridors, elevators, switches and plenty of puzzles, open spaces too, but not too wide (texture glitches), with a large presence of enemies, but not in swarms (evident slowdowns).
    Hell Revealed, the one I have tried the most, has all these requirements and on gba it makes a very good impression.

    Im glad to hear that it worked well for you! I am currently working on simplifying maps for requiem.wad for gba, because the maps have either overly complex maps or too many things in the map.

    I don't know how possible it would be, but I'd love to see
    DOOM 4 VANILLA

    too much reliance on dehacked files

    I figured either that or because of RAM limitations. That said, the list you've began with thus far is PRIME!

    Requiem is an excellent choice: this megawad, by the same authors of Memento Mori and dating back to 1997, is one of the most popular and innovative wads of that period.

    A personal thought: I still remember when, returning from school, I bought a copy of a videogame magazine containing the shareware version of Doom95.
    I tried it on my 386 PC, and I was immediately impressed; it seemed like a unique, exceptional and incredible game. Since then it has remained, for me, a point of reference and comparison to judge subsequent FPS.

    And then I remember the first controversies about the violent nature of this game, and the potential negative influence on the development of the character of young people.
    Personally I have never perceived its violence, because I considered it, with a metaphor, as throwing stones at ripe fruits, of different shapes and colors...:rofl2:

    Who would have imagined, that 25 years later, I would have continued to experience the same sensations and fun, even playing it in pocket format...:rolleyes:

    Forgive my ravings.

    Alright, so I decided to take a break from simplifying maps on requiem and decided to take a stab at simplifying alien vendetta levels. Only up to level 6 is playable, and level 6 may crash. Please let me know if there are any problems with these downgraded maps that I can fix.

    i tried and it reconizes the game as doom 2 and requests doom 2 maps and textures. How do i get it to recognize it as doom 1?

    IIRC FreeDoom Phase 1 has a similar issue. I may try to do Deathless myself but remove code to detect a Doom II IWAD.

    Sorry if I report a little personal experience.
    While previously, playing with Hell Revealed, one of the oldest and simplest vanilla wads, I considered it perfect and very suitable for the small Nintendo console, arrived at map14 I have to reconsider my judgment.

    Immediately at the beginning of this map there is a slowdown, which worsens as you proceed, due both to the excessive presence of enemies, and to the too wide and open environment. The game does not crash but slows down to the point of becoming absolutely unplayable.
    Previously, too, there were strong slowdowns, especially in the presence of multiple giant mechanical-spiders or minotaur-like beings, especially in the presence of many of their projectiles.

    I don't know how and if it is possible to easily decrease the number of enemies, but keep in mind, in converting the wads, that even with the simplest ones there are such slowdowns as to ruin the gameplay and make everything unplayable.

    I wait for others to report their experiences, and I write below, for those unfamiliar with them, some cheats codes for the GBA version of PrBoom, which can be activated through button combinations:

    Chainsaw: L, UP, UP, LEFT, L, SELECT, SELECT, UP
    God mode: UP, UP, DOWN, DOWN, LEFT, LEFT, RIGHT, RIGHT
    Ammo & Keys: L, LEFT, R, RIGHT, SELECT,UP, SELECT, UP
    Ammo: R, R, SELECT,R, SELECT,UP, UP, LEFT
    No Clipping: UP, DOWN, LEFT, RIGHT, UP, DOWN, LEFT, RIGHT
    Invincibility: A, B, L, R, L, R, SELECT, SELECT
    Berserk: B, B, R, UP, A, A, R, B
    Invisibility: A, A, SELECT,B, A, SELECT, L, B
    Auto-map: L, SELECT,R, B, A, R, L, UP
    Lite-Amp Goggles: DOWN,LEFT, R, LEFT, R, L, L, SELECT
    Exit Level: LEFT,R, LEFT, L, B, LEFT, RIGHT, A
    Enemy Rockets (Goldeneye): A, B, L, R, R, L, B, A
    Toggle FPS counter: A, B, L, UP, DOWN, B, LEFT, LEFT

    I converted someone's duke 3d stage 1 remake to the gba. Now you can clearly see that duke nukem advance could have been way better! Also, here is a quick and dirty conversion of the first stage of doom 64, dont expect anything to work past stage 1, they are both mostly tech demos. (I think doomhack should try porting heretic to the gba, i would like to see that happen!)

    As per request from nikokaro, I found a wad that matches the description of being small, and fun to play with little enemies, its called Baculus. I converted it to gba, and all the levels should work, since the enemy count never tops 400 in any stage, and the geometry is simple and small.



    -edit) the original file posted was not working properly, so I reuploaded my fixed version. Everything should work just fine now.

    -Edit2) Due to the way I "fixed" the other version, the wrong texture would show up for the majority of textures, like the vines hiding the red key for example. This version fixes this problem, everything will work, LAST EDIT!

    I tried the first map of Baculus and it looks very promising: it will be the next one I will play.

    As for Duke3d and Duke64, my policy is to use megawads only; I leave them to others to test.

    Changing the subject, I seem to understand that for Freedoom1 or Freedoom2 you have not found a way to convert them; it's a pity because it's the only PrBoom compatible (that I know of) with creative and original textures / enemies / weapons.

    Thanks again for your continuous, hard (and unpaid) work in favor of all of us.:D

    Incredible work. Are these easy to patch into the original ROMs?

    For the most part, yes. All I have to keep an eye out for is sidedef file size and amount of things in the map.

    — Posts automatically merged - Please don't double post! —

    I am going to share two completely working megawads and one experimental wad. Doom nmd is like dtwid but with a more refined, straight to point approach to its levels, closer to the original doom than dtwid, imo. Wonderful doom is a complete reimagining of doom 1. Enjoy!

    Baculus is a prepatched rom and is ready to use.
    The files in the opening post are in .xdelta format and must be patched on Doom.gba.
    As for me, I use Unipatcher on Android.

    Edit: Oops ... maybe I misunderstood the question ...:rofl:

    Can Sonic Robo Blast 2 be ported? I believe it's a DOOM "total conversion" game.

    If anything, it relies too heavily on dehacked, which cannot work on prboom gba. So no, it will not be possible to convert it to gba, unfortunately
