My son has autism and is 8. I dont play this game but I find him mods that he wants. He watches youtube videos and points to it telling me he wants it. I try to find it but MOST are 1.8. I have forge installed and Optifine 1.12 and then soon 1.13.
Hes SUPER into lucky block stuff. I have the lucky block mod installed and like 5 or 6 add ons, for the lucky block but he'll find some that needs loot++ and I can't get that to work and or he'll find older versions of lucky block add ons that don't work. I guess my questions are:
is it possible to get an older mod to work with a different version of minecraft? is there some trick that I just dont know?
I dont play this game but I have to do all the installing for my son so I guess that is why I am super confused.  I've tried searching for answers but I guess I am not wording it right. I keep getting old content or stuff not pertaining to my situation.
Like I'll dl the mod and drop the folder in add ons> lucky block but sometimes they do not show up with all the other stuff.
Example:
Frosty lucky block. He saw it on a video. I went and downloaded it. Dropped the folder in the add> lucky block
He starts the game and the frosty block isnt in with all the other blocks.

is it possible to get an older mod to work with a different version of minecraft?

No, this is a fundamental thing with Minecraft modding. Mods {for the most part} only work for one specific Minecraft version.

Unfortunately no, since it is specific to the MC version. Is there any alternate to this?

That is correct one version per Minecraft version. There are a FEW exceptions but the mod author will let you know if that's the case.  

 

The water downed idea is that Minecraft is "encoded" (non open sourced) and therefore every single update it's "mixes" the code even more. So even a minor update could render a mod useless...

If you want to, you can create a script and then a bunch of desktop shortcuts that can allow you to switch between mod directories easily.

 

If you copy the copy below into a file called switchmc.bat and replace YOUR_USER_NAME with your computer's account name, then you can make desktop shortcuts to this file and add the mane of the mods directory to the target property.

 

E.g. if you save switchmc.bat into C:\ then create a shortcut called swichmc 1.8.9, right click, and then change the target to say C:\switchmc.bat 1.8.9

 

Now you can put all your 1.8.9  mods in a directory called mods_1.8.9 (in your .minecraft directory). 

 

It makes it faster to switch between versions of Minecraft. You still need to install forge for each version of minecraft and make a profile for each version.

 

Let me know if you need any help.

Or you could just use the Profiles functionality of the Minecraft Launcher.

Or MultiMC. That why it was made to make the operation of owning multiple versions/packs/etc a breeze.

Meh. Since the official profiles feature was introduced this should be killed with fire.

Some tips i posted in another thread about how to use profiles:

I would argue that it still a simpler operation for adding/removing mods to boot. As far as I know that where the Vanilla launcher hits the fan. Likely due to not being geared for this purpose.   

 

Ho and it's way easier to install/update Forge as well.
