120 seconds to boot can I make it shorter (pizero)

[twd]

Atm on my pi zero I have 50 roms installed other apps installed are stephselph scraper and the retropie browser manager
it's a modest setup no bells and whistles, I have disabled the Es_loading screen as I cannot se a way to replace it and I also got rid of boot text.
My start up video is 10 secs long and after and starts at 11 secs at boot time and finishes at 21 sec's this leaves me with 100 sec of black screen. What are my options start deleting systems or masking the issue . Love to hear some ideas I am at a loss
