Exhibit 10.4

AMENDMENT

Reference is made to each of those certain Subscription Agreements (the
‘‘Subscription Agreements’’), dated January 17, 2007, by and between Handheld
Entertainment, Inc. (the ‘‘Company’’), and each of the subscribers for Units (as
defined in the Subscription Agreement), to each of those certain Warrants to
Purchase Common Stock of the Company at an exercise price of $4.00 per Share
(the ‘‘$4.00 Warrants’’) and to each of those certain Warrants to Purchase
Common Stock of the Company at an exercise price of $3.50 per share (the ‘‘$3.50
Warrants’’) issued to subscribers for Units. Capitalized terms used herein, but
not otherwise defined, shall have the meanings ascribed to such terms in the
Subscription Agreements, the $4.00 Warrants or the $3.50 Warrants, respectively.

In consideration of the premises and mutual agreements herein set forth and
other good and valuable consideration, the receipt and adequacy of which hereby
are acknowledged, the undersigned agree as follows:

[spacer.gif] [spacer.gif] [spacer.gif] 1.  No provision of Section 5(b) of the
Subscription Agreements shall apply to the $4.00 Warrants, and such Section 5(b)
is hereby amended to read in its entirety as follows:

‘‘Subject to the provisions of Section 5(f) below, (i) if the Company fails to
file the Registration Statement with the SEC on or prior to January 31, 2007,
then the exercise price of the shares of Common Stock underlying the $3.50
Warrants (the ‘‘$3.50 Warrant Shares’’) shall be reduced by 10% of the original
exercise price or (ii) if the Company fails to obtain effectiveness of the
Registration Statement by the SEC on or prior to March 15, 2007, then the
exercise price per $3.50 Warrant Share shall be reduced by 20% of the original
exercise price; provided, however, that if the exercise price has been reduced
pursuant to clause (i) above, then the exercise price shall only be reduced by
an additional 10% pursuant to this clause (ii). To the extent the Company has
failed to obtain effectiveness of the Registration Statement by the SEC on or
prior to March 15, 2007 (and the exercise price has been reduced by an aggregate
of 20%), then at the end of every 30 day period thereafter that the Company has
still not obtained the effectiveness of the Registration Statement, the exercise
price of the $3.50 Warrants Shares shall be reduced by an additional 10% of the
original exercise price.’’

[spacer.gif] [spacer.gif] [spacer.gif] 2.  Section 8 of each of the $4.00
Warrants is hereby amended by deleting the words ‘‘Reset of Warrant Price’’ from
the heading thereof, and by deleting paragraph (b) thereof in its entirety.

and construed in accordance with the internal laws of the State of New York,
without reference to principles of conflicts of laws. Any dispute involving this
Amendment or the agreements referred to herein shall be brought only in the

assigns of the parties hereto.
