Phaeron w końcu opublikował nową wersję Altirry, obecnie najlepszego emulatora małych, ośmiobitowych mikrokomputerów firmy ATARI. Z rzeczy, które warto odnotować, a które zostały opublikowane w nowej wersji warto wymienić dodanie emulacji DragonCart (sieć dla XE/XL), dodanie obsługi standardu The!Cart czy też obsługę updejtu atarek w postaci 65C816. Zapewne 2.50 pojawiło by się szybciej, gdyby nie awaria komputera Phaerona, odbudowanie bazy deweloperskiej chwilę mu zajęło.
