Emulators! A lot of work and multiple skillsets and needed to make a working emulator, let alone an accurate one, yet most of these projects demand no payment.
I contribute to the BizHawk frontend, which doesn't currently take donations. But when it does, we'll definitely be paying it forward to the many "emulator core" developers whose FOSS projects allow us to claim 40+ systems emulated.
I'd like to shoutout alyosha, who recently left our team but has contributed many bespoke cores and remains active in hardware research circles; and also endrift, the solo dev of mGBA; LIJI, the solo dev of SameBoy; Arisotura, the solo dev of melonDS; and Eke-Eke, the solo dev of Genesis Plus GX.
