Yes please. The current implementations differs in a number of ways though they shouldn't. It has 64 sprites (no more, no less), Iron Horse has missing/flickering sprites in MAME because the driver specifies too small sprite ram (256 bytes when it should be 320 bytes). Sprite sizes are 32x32, 16x16, 16x8, 8x16 & 8x8. The only difference between the games are how the tile code is calculated (and Jackal using 256 color bg tiles). Interrupts should also be handled in a more common way (same as 005849). I have all 4 games running on a Nintendo DS with the same sprite/bg/irq driver.
