It's possible to fire every frame by alternating button presses except in c system version, which only has one button. Blocks dropped fall one line per frame, and up to 8 may be on screen at once, though only the most recent is visible. Lines cleared by Flicky do NOT count towards level progression. Bravos can be scored with Flicky, with the usual 10x multiplier.

It is possible to make line clears greater than 4 at once, but five is scored as if it were one, six as if it were two, etc. After landing on the stack, Flicky disappears and normal gameplay resumes. During its descent, it can be moved left and right, and made to drop single blocks (of which it has an infinite supply) by pressing the rotate button.

This converts some S and Z pieces into I pieces. If the flag is set, modulo results of 1 and 2 are treated as 0. Then, if the value before modulus is greater than $6f, a flag is set. When generating pieces, the result is ANDed with 0x7f instead of 0x3f. It runs this once, and takes all 32 bits of the result (not the new seed), and stores it to use as the seed for the piece generator. The initial seed is one higher, at 0x2A6D365B.
Trash it sega generator#
Bloxeed reuses the random number generator from Tetris (Sega), but adds a few changes.
