HYPER*

This a cheat code? In that case HYPEROFF for fast repair at the boxes of F-1 Spirit... or HYPER in Nemesis to get all weapons.

Hyper for nemesis

here is a new one : Cosmic

I want to hear atleast 2 games

Cosmic -> two games from the same publisher:

Blow-Up and Vortex Raider

vamp: I asked for two

winter hawk is another one...

I was actually pondering whether or not I was gonna ask that same question with cosmic

I always liked this one:

hoihoihoinohoi

shouldn't be hard though

hoihoihoinohoi -> Hinotori (Firebird)

kazumi?

What about this one:

HENK HENK HENK HENK
HENK HENK HENK HENK
HENK HENK HENK 5

Or is it not my turn yet

The henk thingy must be a weird MoG code, Kazumi is also a Konami one (figures, it's from BiFi) from Penguin Adventure. It's almost identical to NORIKO.

Now for a new one...
uhm.... 'Ken sent me', no that's not MSX.... ehhh...
U,L,D,L,D,U,U,L
with L=left cursor, U=up and D=down

Try this too:

Right, right, left, left, up, down, left, down, down, down -> Test mode

Uh.. Gulkave?

I think it's some bubble bobble code

Correct, BiFi!

Yes, Gulkave! Great!

Another:

Power on MSX with the game inserted and cursor-up key pressed while booting.
