[SC64][BUG] TV Struggle to detect video output of the console

[BH3Panzer]

Is your issue really a bug?

• I understand the difference between flashcart firmware, N64FlashcartMenu and sc64deployer PC app.
• I found a bug in FPGA HDL (/fw/rtl)
• I found a bug in MCU app (/sw/controller)
• I found a bug in N64 bootloader (/sw/bootloader)
• I found a bug in PC app (/sw/deployer)
• I found a bug in initial programming script (/sw/tools/primer.py)
• I found an error in documentation (/docs)
• I found an issue elsewhere

Firmware version

v2.20.2

Describe the bug

I have a PAL N64 console from late sales, using a flat polaroid TV with SCART.
I have a issue where some games in direct boot or from N64FlashcartMenu with PAL forced have a sped up and glitchy sounds with broken graphics (left red line, not centered, cropped).
And other games like romhacks where the original has problem but the romhacks has no problem at all.

The ONLY difference I have seen between these games is that my TV shows PAL60 for bugged ones and PAL for those that don't have problem.

The PAL60 originals and PAL romhacks are both NTSC roms at the start.

Classic PAL roms don't have any issues at all on TV because there are detected as PAL directly.

The problem is maybe the TV but I wanted to know if there is any workaround for this like forcing PAL output and making TV to PAL mode (I can't change the input of TV manually).
