Hi! I Have found 3 Leonardo games (Italian Arcadia 2001), variations from GIG:
Astro Invader: GIG version, not listed on dp's guide, licensed by konami (LICENSED ARCADE GAME on the box), © UA Ltd. 1982, long cartridge. On the box (side) and back label is written CART.# 32.
Soccer: GIG version, not listed on dp's guide, © UA Ltd. 1982, short cartridge. On the box (side) and back label is written CART.#16.
Grand Slam Tennis: GIG version, listed as Unconfirmed (no more!) on dp's guide, © UA Ltd. 1982, long cartridge. On the box (side) and back label is written CART.#22.
That's all.
