The Retrollectors – Mayflash F300 CUSTOM Dreamcast Controller MOD | The Retrollectors | Today I modified a Mayflash f300 arcade stick to resemble one of my favourite arcade sticks of all time. The Dreamcast HKT 7300, I swapped out the stock Mayflash buttons and arcade stick to a Sanwa JLF Arcade stick and Sanwa OBSF buttons. The modification doesn’t end there, I felt that I wanted to replicate the Dreamcast HKT 7300’s overall look so lets change that and add some Mayflash artwork to revamp its stock look.
