240pTestSuite VS cave-story-md

If I might add: using 240pTestSuite or something similar (there are specific hardwares to output a grid signal and the likes) is a good way to check for convergence issues or bad picture quality overall.

The grid array you’re referring to is the 480p Test Suite and it’s available for several different consoles and Everdrives. There are several different test patterns in the suite that can help adjust the CRT’s geometry. I actually have your exact same model of Sony (love all the inputs) and have the geometry dialed in just right. You’re correct, you will need the original remote to get into the advance menu for geometry adjustment. IMPORTANT - Make sure to write down any numbers BEFORE you make adjustments just in case you need to revert back to them! The internet is your friend here, as there are several guides out there for making these adjustments in these menus. Good luck!

240p Test Suite GitHub

I've open [feature request for ogxbox version of 240pTestSuite, but probably won't come in a near future.

You need hardware that can run 240p test suite, for example a Wii with homebrew channel or an Everdrive cart for Snes. https://github.com/ArtemioUrbina/240pTestSuite

You can also affect geometry with thin magnets. My 32AX60 has 4 arrow( ^ ) magnets iirc, which I might adjust slightly. You can use one of the built-in test patterns on Toshiba's service menu(toggle with TV/Video while in Service Menu) while doing this adjusting... like the Toshiba dark background with white lines & dots grid, or the color bar grid in 240p Test Suite https://github.com/ArtemioUrbina/240pTestSuite/blob/master/240psuite/Wii/240pSuite/textures/color_grid.png I think the monoscope & convergence patterns were/are being added too to Wii so those might be better idk. But the color grid works well for adjusting side or corner convergence imo.

There's a Genesis port of Cave Story, in case you've missed it.

There is a Genesis port also: https://github.com/andwn/cave-story-md

Link to the port here: Cave Story MD

It's also highly accessible and available on an insane amount of platforms. You could play it on emulator handhelds from 2008 that could barely handle SNES. You could play it on a Dreamcast or a PSP or an Amiga PC. There's even a port in progress for the freaking Sega Genesis of all things.

Cave Story for Mega Drive

Very cool. I've been playing the Megadrive version recently. It makes some concessions that I imagine the PSX port wouldn't have to.
