Original ROMs for ZA1JS20G and ZA1JU01A00G

Hi, in my ECU research I've collected a bunch of stock ROMs, and I have two that aren't on the forum yet, S20G and U01A. Both are manual shift, red intake, and non-US.

ZA1JS20G says it's "AL7 H4NA - EU - 6MT - 2018" at 0x8000, "BSW_12CYH4N_DI_MC5 Ver 1.00r1" at 0x8100, ecuid 0xBF61707007 at 0x12947b.

ZA1JU01A00G says it's "AK8 H4 - DOM - MT - H - 2018" at 0x8000, "BSW_12CYH4N_DI_MC5 Ver 1.00r1" at 0x8100, ecuid 0xC901703107 at 0x125924.

These are both interesting to me because they have EU/JP MC5-series logic, rather than the US MC4-series logic in the US roms. I've been digging into VVT and there's considerable differences in how intake/exhaust timing are calculated, along with total rewrites of the base/normal/safe tables.
  • K00A: AN5; MC4, 1.00r1
  • K10C: AN5; MC4, 1.20r1
  • N01A: AM6; MC5, 1.00r1
  • N10C: AM6; MC4, 1.20r1
  • Q00G: AL7; MC5, 1.00r1
  • S10C: AL7; MC4, 1.20r1
  • S20G: AL7; MC5, 1.00r1
  • U01A: AK8; MC5, 1.00r1
  • V00C: AK8; MC4, 1.20r1
(No XMLs for these at this time, sorry. Maybe someday!)
