Metal Slug 5 Plus

[terminator2k2]

just wandering if the game mapper/rom bank switching could be added for metal slug 5 plus rom to the core?

OK, so in order to provide support for Metal Slug 5 Plus I have been informed that there needs to be a custom bankswitch mapper at 0x2FFFFX, here is the relevant Mame code

Code: Select all

case NEOGEO_MSLUG5P:
            space.install_read_handler(0x2ffff0, 0x2fffff, read16m_delegate(*m_slots[m_curr_slot], FUNC(neogeo_cart_slot_device::protection_r)));
            space.install_write_handler(0x2ffff0, 0x2fffff, write16sm_delegate(*this, FUNC(neogeo_base_state::write_bankprot_ms5p)));
            break;

Special function:

Code: Select all

void neogeo_base_state::write_bankprot_ms5p(offs_t offset, uint16_t data)
{
    logerror("ms5plus bankswitch - offset: %06x PC %06x: set banking %04x\n", offset, m_maincpu->pc(), data);

if ((offset == 0) && (data == 0xa0))
{
    m_bank_base = 0xa0;
    m_bank_cartridge->set_base((uint8_t *)m_slots[m_curr_slot]->get_rom_base() + m_bank_base);
}
else if (offset == 2)
{
    m_bank_base = m_slots[m_curr_slot]->get_bank_base(data);
    m_bank_cartridge->set_base((uint8_t *)m_slots[m_curr_slot]->get_rom_base() + m_bank_base);
}
}

There are a number of other Mappers in Mame for other unlicensed games, some of which seem to come from a big yellow coloured Chinese bootleg cart and worked on original hardware. You can see the code for these different games here:

Now, can someone help me figure out what the following games are? Three of them are presumably versions of The King of Fighters 2003, but what are their variant names?

CTHD2K3 = Crouching Tiger Hidden Dragon 2003
CT2K3SP = Crouching Tiger Hidden Dragon 2003 Super Plus
MSLUG5P = Metal Slug 5 Plus
KOG = King of Gladiator
KOF2K3B = ?
KOF2K3UP = ?
KOF2K3P = ?
SBP = Super Bubble Pop
KOF10TH = The King of Fighters 10th Anniversary 2005
JOCKEYGP - Jockey Grand Prix
VLINER = V-Liner

If we can figure these out then there is enough info now to get fleshed out tickets in GitHub and there is a chance a developer may be willing to add support. At least some of these should be pretty simple to add.

At a guess...

CTHD2K3 = Crouching Tiger Hidden Dragon 2003
CT2K3SP = Crouching Tiger Hidden Dragon 2003 Super Plus
KOG = King of Gladiator

Big thank you, to Sorgelig for adding the Metal Slug 5 Plus rom banking, much appreciated

Didn't it already work before if you used the .neo file?
