This game often backups hero structs. And, if a hero struct has wrong checksum/CRC, the game restores it from the backup. I crafted a fake backup struct on SRAM (with z3 solver), and created an amulet by changing name.

On Famicom version, the game displays a logo every time you reset, so this movie is not so fast. If this save glitch can be executed on NES version, it will be quite fast. But, it might be more difficult to execute this on NES version, because you can use fewer character kinds for a hero name.

This improves narimasa's TAS on nicovideo (part1, part2, part3) by about 16 minutes.

Objectively, this game will be quite bad. But it was interesting for me to optimize this run.

EDIT: if you newly tas this game, probably you should use NesHawk/SubNesHawk. Because, this game doesn't use NMI and uses PPU_STATUS ($2002) to wait VBLANK. FCEUX doesn't emulate the race-condition of PPU_STATUS, so an effective FPS differs between FCEUX/NesHawk. (FCEUX: 60.10, NesHawk: ~58. for details, see NesDev Wiki)

On SubNesHawk, You might be able to avoid the drop-frames by using the sub-frame pauses, but it will need the dev-build of BizHawk, because BizHawk 2.9.1 doesn't support FDS disk operations on SubNesHawk.

I made this in 2009, and now resynced this for FCEUX 2.6.6 (just removed some frames).

I couldn't resync this for NesHawk. (desynced at stage 2, and FDS load times quite differ)

Probably highest, but I haven't completely understood about the RNG.

Probably highest, but...

I didn't care about hash collisions, so some unfortunate collisions might hide the optimal solution (though I think this probability is low).
I haven't completely understood about the RNG.

You can zip through some obstacles with U+D / L+R inputs.

When Kazemaru joins, his level will be (the main hero's level) - 1. So, if the main hero's internal level is 0, Kazemaru's internal level will be 255.

But anyway, you have to win the 1on1 battle against the last boss, and it will take a long time to earn levels. I hope there are some more glitches to solve this problem.

Just a testrun. Probably improvable with better RNG manipulation, etc.

When a ball bounces by bumpers etc., you can sometimes manipulate the direction of the ball with input. (Probably the address $5A affects.)

This movie syncs on NesHawk as is, but I confirmed that another .fm2 movie only partially syncs on NesHawk.

Memory map:

addr	type	description
$37	u16le	ball position x (subpx)
$39	u16le	ball position y (subpx)
$3B	i16le	ball velocity x (subpx)
$3D	i16le	ball velocity y (subpx)
$5A	u8	affects the bounce direction of the ball (can be manipulated with input)
