 othldrby - オセロダービー (日本版) | ||||
| 概 要 | 5キーでクレジットを入れた後、6キーを押してもクレジットが入らない。5なら続けて入る。同じく6で始めたときには5は使えない。059～062で確認。 | ||||
| 詳 細 | When you insert a credit using 5, then you insert another credit using 6, it won't accept it. If you keep inserting it with 5, it gives you credits. Same goes if you start inserting coins in 6 first, then 5 won't give you credit. You can insert more credits using 6. So bottom line is that whatever you use first to insert the credit, thats the only credit button you can use. The other one won't work. | ||||

| 追加情報 | This strange behaviour exists since the game is emulated. <B>Stephh observations</B>:
From MAME othldrby.c driver :
static WRITE16_HANDLER( coinctrl_w )
{
if (ACCESSING_BITS_0_7)
{
coin_counter_w(0,data & 1);
coin_counter_w(1,data & 2);
coin_lockout_w(0,~data & 4);
coin_lockout_w(1,~data & 8);
}
}
static ADDRESS_MAP_START( writemem, ADDRESS_SPACE_PROGRAM, 16 )
...
AM_RANGE(0x700034, 0x700035) AM_WRITE(coinctrl_w)
ADDRESS_MAP_END
The only place where there's a write to 0x700035 is here :
0001E8: 13F9 0010 2F7A 0070 0035 move.b $102f7a.l, $700035.l
So you need to find when contents of 0x102f7a changes ...
During initialisation, 0x102f7a is set to 0x00, so both coin slots are locked.
After initialisation :
0002F6: 0039 000C 0010 2F7A ori.b #$c, $102f7a.l
So both coin slots are now unlocked.
When you press COIN1 (A0 = 0x102f70) :
000660: 08E8 0000 000A bset #$0, ($a,A0) Trigger coin counter 1
000666: 0239 00F3 0010 2F7A andi.b #$f3, $102f7a.l Lock both slots
...
000676: 08A8 0000 000A bclr #$0, ($a,A0) Untrigger coin counter 1
00067C: 0028 0004 000A ori.b #$4, ($a,A0) Unlock slot 1 (but slot 2 remains locked)
When you press COIN2 (A0 = 0x102f72) :
0006A0: 08E8 0001 0008 bset #$1, ($8,A0) Trigger coin counter 2
0006A6: 0239 00F3 0010 2F7A andi.b #$f3, $102f7a.l Lock both slots
...
0006B8: 08A8 0001 0008 bclr #$1, ($8,A0) Untrigger coin counter 2
0006BE: 0028 0008 0008 ori.b #$8, ($8,A0) Unlock slot 2 (but slot 1 remains locked)
