Tam Tam Twins is the same game as Chiki Chiki Boys, isn't it?
Chiki Chiki Boys is the Japanese name of "Mega Twins", that Capcom side-scrolling platform, right?
IMHO it has something that reminds me Super Mario Bros 2... actually it looks like BC KID was entrapted in a SMB2 level while he was wearing a blue pyjama :)
Ah, just kidding... the graphics is actually looking stunning to me... is it really running on a MSX1 machine ?
Indeed, the graphics is stunning 
Short videos while girls strip their clothing ....
humm...
So, what are you waiting for? 
funny, you can't "avoid flickering" since "flickering" is a software build method to avoid (and here it comes) invisibility of sprites.
You see, when more than 4 sprite (lines) are on a horizontal line, that line magically disappears on all sprites with a higher plane nr than those 4 sprites.
A "flickering", or interlacing, routine is a good creative solution to have all sprites visible, at least for a moment of time. With high framerates that interlacing get faster.
So, wolf, get cracking on multi layered sprites (you know, a black outline to clearly separate sprites from backgrounds...). We love interlaced sprites 
(see how Konami does that trick and why they maintain great gameplay)
