hi everyone! i finally decided to start speedrunning. i have a lot of games in mind that i loved in this years. any suggestion on how can i record on a ps2 console without emulators? really thanks!!

If you're recording from console, you need a capture card to capture the game feed. An affordable and high quality for consoles like the PS2 or earlier is the gv-usb2. You can find it for sale on most sites like amazon and ebay, and there are tutorials on how to install the drivers for it (they are in Japanese but it only requires 2 clicks so it's hardly a difficult thing).
