I replaced by HazeMD 0.04a. It supports "real" Reset Button on Genesis/Megadrive. It enables "safe" reset. For example on Burning Force, MAME soft-reset causes the crash but real-reset is without problem.
And you can avoid ROM check in case of real-reset.
I have confirmed Round Select Mode on M.U.S.H.A / Musha Aleste on HazeMD.
But sorry, I have mistaken about how to enable it. Correct way is...
I have tried to search for SMS/MarkIII game but...

If you use Round Selection and "Game Over" on the same round, "Continue Game" always gives starting with Round 1.
But correct value is stored into $C843 when you finish this round.
[TIPS]
- Round 0 -
Select "Continue Game" after you see the ending, the game start with Round 0.
- Sound Test -
On title screen, input "Up, Down, Up, Left, Left, Down, Right, Up" then press a button.
- Start with 10 lives -
On title screen, input "Down, Right, Down, Down, Left, Right, Left, Right, Up, Right" then press a button and start the game.
- Enable to continue with Round 6 -
Normally, "Continue Game" don't allow to start with Round 6.
If you do "Game Over" on Round 6 then re-start with "Continue Game", the game starts with Round 5.
But hold Left then select "Continue Game", you can start with Round 6.
- Cut FM sound -
When power-on, hold 1P Upper-Right and 2P Lower-Left.
the game has PSG sound only instead of FM.
But HazeMD doesn't have SMS/MarkIII FM sound emulation so that it is meaningless (always PSG).
My Master System which includes FM sound chip is dead now...
...It is main problem that I can't hack a program code.
I have tried to make "Always Start with Round 0" and "Unlimited Continue Round" with ROM code.
If you select "New Game", 0x01 loaded on $0BA2 is stored into $C881.
So I want to change "ld a,$01" on $0BA2 to "ld a,$00".
And in case of "Continue Game", I want to kill "jr c,$0BB4" on $0BB1 (->"jr $0BB4).
...Never work.
On sms.c
s_aleste seems to be loaded into USER1. But changing "20x00000" (Region-CPU1) to "39x00000" (Region-USER1) is meaningless. Also different address...
I have already checked these codes via Windows memory editor (works fine !) but I don't know how to confirm via the cheat engine.
Pugsy, can you hack any rom code on SMS ?
And you can avoid ROM check in case of real-reset.
I have confirmed Round Select Mode on M.U.S.H.A / Musha Aleste on HazeMD.
But sorry, I have mistaken about how to enable it. Correct way is...
- Press Reset button 10 times.
- On title screen, hold Lower-Left then select Options.
- Confirm that "SOUND" item changes "ROUND".
- Select round you want to start then press Start button or exit Options.
- When displayed "SEGA" logo, press Reset button.
- Start the game
- Life and Credit are 255 !!
