I'm trying to make a SRC logo for games i moderate (Security Breach & Cookie Run Kingdom), how would i make a SRC logo out of the actual game logo, if the game logo doesn't have the letters i need (does that make sense?)
You can use an online tool to try and find the same or a similar font and then use that for your logo
Yeah, when making game themes I usually use Photoshop, although GIMP is a solid free alternative.
One thing I recommend, similar to what Bacon was saying is to use a website to help you find the right font. I recommend https://www.myfonts.com/WhatTheFont/ personally. I'll usually find a similar font, type in Speedrun.com into the example box, zoom into the page so its as big as possible and screenshot that. Then I bring it into Photoshop and remove the background, and clean it up if need be.
Then you can use the eye dropper to select colours and stuff. I also usually try to include parts of the game's logos or icons in it like I did with https://www.speedrun.com/valorant and https://www.speedrun.com/ghostrunner
