@wyatt I read your post and began to fear that I had misnamed my Game Boy and Game Boy Advance ports of 240p Test Suite. https://github.com/pinobatch/240p-test-mini
"#240p" means 256x240 on an #NES, 320x240 on a bunch of devices, or 400x240 on a #Nintendo3DS Top Screen. And in analog video, it even ends up including devices like #MSX and #NintendoDS that generate roughly System M timings (15.7 kHz by 60 Hz), even if the top and bottom borders are so thick that only 192 lines actually have picture. (#GameBoy and #GBA don't count as "240p" because their horizontal frequency is lower.)
