"Sketch too big" with all modules enabled about cartreader HOT 8 OPEN

You can only enable a few extra modules or else the Arduino Mega will run out of available memory and/or program space.
Try to stay below 90% dynamic memory.

Is there no way to have them all enabled, maybe using a different Arduino with better specs?
Even disabling all the systems I won't use, it's still slightly too big.
Just seems like a waste to have a cart reader for all these systems but it can't really do all of them at once.

I deal with a LOT of systems, and have more adapters than slots. I do see you're on the current 13.1 - the latest master build of 13.2 has a lot of cleanup allowing for more at once. I can enable all mine now (though I may be toying with more than 90%, I'm not sure - no issues yet). Before that, I'd pick something I wasn't planning on dumping for a while, usually N64, then enable some others.

Even with all the systems I dump for, I can usually identify a few I know I won't be doing for a while should I need to disable them. Unlikely I'll be doing 12 consoles in the same week.... However if I do, well, I have 2 OSCRs cause if you're doing that much dumping, you'll run into times one needs some work and you're glad you have another. But while they both work, I can keep them flashed with different stuff.

Though, since the recent cleanup on the 13.2 version that hasn't had a regular release yet, I've been using all I have slots and adapters for with no issue, the footprints were decreased a lot. If I do run into an issue I'll disable N64 until I get more N64 to dump lol. If a random cart does fall into my lap, flashing takes maybe 2 minutes - just keep a PC nearby!

I currently have enabled:
All slots for dumping (not anything special for flashing, I don't do that), on the HW V5.
-Atari 2600, 5200, and 7800
-PC Engine
-Watara Supervision
-Intellivision
-Colecovision
-Odyssey2

So far, so good! But I worked for a long time just disabling N64 as needed.

There isn't a better 8-bit AVR than the ATmega2560. You can reflash it with different options enabled when dealing with different systems. People who often deal with more systems than can be enabled at once will sometimes build multiple OSCRs.

HW7 resolves this problem, but will not be available for some time yet. After I finalize the new HW5 revision I'll begin working on HW7's prototype boards -- the schematics for most of the sections are done (USB, main power, and cart IO). I don't expect it to be ready until next year.

Like him abpve me, I also have 2 oscr's but ive customized one. One oscr is normal and i have additional systems added, and the second oscr is strictly 5v with a gamegear slot with a 7 in 1 on top that handles all 4 atari systems, c64, odyssey2, colecovision and intellivision, which lets me use all the remainder of the systems with adaptors on the first unit. Of ypu really do have that many systems, I do believe 2 devices is the right way to go.

sadly - It is not possible to enable to enable all. ATM the code uses ~117% depending on other options. At 13.1 it was ~135%. So using the latest version will improve the situation alot. I'm confident with further optimization to get down to ~110% maybe 100% (things to try out would include to outsource all string into a SD file, move blacklist handling of MD to a file). But only if no other systems/other features are added which I'm pretty sure will happen sooner than latter mysterious foreshadowing.

I tried this using a JSON file. It does work, but it makes navigating the menus noticeably slower but not so slow that they are unusable. It's at least a few hundred ms though.

yeah i think it would require an cache mechanism.
