If there only stands "Ep128" , the Game was developed/released for the Enterprise, right ?
Not always. It can ba also a CPC conversion. E.g. Turbó Rudi was thought to be an original EP game but not much ago somebody found the CPC game Electro Freddy. It is sometimes difficult to find the original game because it can have different name.
RX-220 also seemed to be an original EP game but somebody realised in 2009 (!) that it isn't.
But how can i see, wich Game is :
1. an officially (commercial) conversion/version for the Enterprise ?
2. only for Spectrum, and then coded by "amateur"-programmers ?
3. first developed/released for Enterprise, and then converted to the Spectrum (don't know, if Spectrum was always the First System for the Games)
A good question... you cannot see it only if we tell you.
Maybe a thorough database of Enterprise programs is still missing, we should create it.
Those who had/have Enterprise computer at home know about what programmes he bought in the shop and what programmes were sold. That's why we know which program is a retail ("officially issued") game which isn't. And, of course, the cassette covers we find on the net (e.g. on E-bay) can tell us more. But those who didn't have an Enterprise computer can't have much information about it because in the program database we didn't write about these things, yes. Sorry about the inconvenience. At any rate we try to help you.
Moreover, I have had an Enterprise computer since about 1988 but I don't know about all the programs if they are original EP programs or not. We always find an original game in some other computer for the game we thought it was originally coded for EP. (E.g. RX-220)
In the wiki here I began to write a list of the original EP games (
here). But I am afraid there are some not original EP games in the list. At any rate, the "Orksoft játékok" (Orksoft games) are original EP games (hello Endi!) but, of course not officially released. At the end of the list you can see "
Eredetinek látszó Enterprise játékok, de nem azok" which means "Games which seem to be original EP games but they aren't".
A good question if there are more officially released EP programs than cassette covers on the ep128.hu. Maybe there aren't.
One more thing: Cassette pack 1-2-3 cassette covers contained cassettes with some programmes you can find on the ep128.hu but I am not sure which games they contained.
I think we have to create now a thorough list about the original EP games, about the conversions and about the official (retail) games...
